This is a question that can be Explain the wave model of light very simply, or be made exceedingly complicated. A simple way to answer is to say that light is a type of wave that causes objects to be visible to human eyes. My bosses tits sun produces light, and that light bounces off objects and into our eyes. This makes it so that we can see things, because the brain can interpret that light and tell us what's out there. But what is light actually made of? How does it work? That deeper question is answered by physics. And it took centuries to figure out. An important step happened in the early 20th century: That might seem Pictures of preetens boobs. It might make you scratch your head, and that's certainly the way physicists felt about the idea at first. But thanks to Male genital thrush symptoms Einstein and Max Planck, we know that light can act like a particle or like a wave, depending on the circumstances. This is called wave-particle duality. The wave theory of light was the way we first understood light. The theory was spread most significantly by Robert Hooke and Christiaan Huygens in the 17th century. They predicted that if light was a wave, we would see certain things. We would see that light could reflect off shiny surfaces, refract or bend...

Light is an extraordinarily interesting phenomena. Although we know light to be a form of electromagnetic radiation and that visible light is merely a tiny section of the electromagnetic spectrum, the propagation of visible light can be modeled in three ways. The models of light are:. The informal and intuitive way of showing light propagation is via the Ray Model. In the Ray Model, light is generally drawn or described using a system of direction indicated arrows. The rays merely indicate the path of the light. This is natural as we have all seen beams of light shine through clouds or car headlights light the road in front of the vehicle. However this is a very simplistic way of describing light. The Ray Model uses ray diagrams to explain things like how lenses focus light, how reflection of light works and how light is distorted by transparent materials of differing densities like glass or water. The wave model describes how light propagates much like how ocean waves move through the water. It is more complicated than the Ray Model and takes into account wavelength and frequency. As the Wave Model incorporates wavelength it can be used to explain colours. The Wave Model accounts for the performance and distortion of light when interacting with objects and openings that have sizes similar to the wavelength of light. Although the Wave Model is applicable for the interaction of light with some relatively large objects, it is generally used when light is associated with objects under a micron in size. The Particle Model for light is required to gain an understanding of how light performs at atomic levels. When light interacts with atoms, it performs as if it is comprised of tiny grains or particles of solid matter. Also known as the Quantum Optics...

An age-old debate that has persisted among scientists is related to the question, "Is light a wave or a stream of particles? The fact is that light exhibits behaviors that are characteristic of both waves and particles. In this unit of The Physics Classroom Tutorial , the focus will be on the wavelike nature of light. Light exhibits certain behaviors that are characteristic of any wave and would be difficult to explain with a purely particle-view. Light reflects in the same manner that any wave would reflect. Light refracts in the same manner that any wave would refract. Light diffracts in the same manner that any wave would diffract. Light undergoes interference in the same manner that any wave would interfere. And light exhibits the Doppler effect just as any wave would exhibit the Doppler effect. Light behaves in a way that is consistent with our conceptual and mathematical understanding of waves. Since light behaves like a wave, one would have good reason to believe that it might be a wave. In Lesson 1, we will investigate the variety of behaviors, properties and characteristics of light that seem to support the wave model of light. On this page, we will focus on three specific behaviors - reflection, refraction and diffraction. A wave doesn't just stop when it reaches the end of the medium. Rather, a wave will undergo certain behaviors when it encounters the end of the medium. Specifically, there will be some reflection off the boundary and some transmission into the new medium. The transmitted wave undergoes refraction or bending if it approaches the boundary at an angle. If the boundary is merely an obstacle implanted within the medium, and if the dimensions of the obstacle are smaller than the wavelength of the wave, then there will be very...

After doing the Find Out Activity on p. When light passes through a small opening, it spreads out around each side of the opening. To explain this, Dutch scientist Christiaan Huygens suggested that light travels in a wave, not as a stream of fast moving particles. The high parts of the wave are called crests. The low parts of the wave are called troughs. The distance from crest to crest is called wavelength the distance from one complete crest and one complete trough. The height of the crest or the depth of the trough from rest position is called the amplitude. The Frequency is the rate at which the crest and the trough move up and down. The number of cycles in a period of time - which is usually measured in hertz , or cycles per second. The wave model of light pictures light travelling as a wave. It doesn't explain everything about how light behaves but it helps us visualize it. Thinking about light travelling in waves helps to explain unpredictable behaviour, like when light curves around a opening. When light passes through a small opening, the waves spread out. If the wavelength is short, the waves spread out very little, whereas longer wavelengths spread out more. Wavelength is explored more in the labs for this topic. Sunsets can be explained using the wave model of light. As light waves from the sun travel through Earth's atmosphere, they strike particles of different sizes, including dust and other elements. The longer wavelengths of the reds and oranges tend to pass around these particles, whereas, the shorter wavelengths of blue and violet , strike the particles and reflect and scatter. At sunset, the light we see passes through about kms of the Earth's atmosphere. There are many more particles in...

What is Light?

Jul 11, - However, they are different than this wave-particle model of light. . explained with a classical wave model of light along with a quantum model. Light behaves as a wave - it undergoes reflection, refraction, and diffraction just like any wave would. Yet there is still more reason to believe in the wavelike nature of light. Continue with Lesson 1 to learn about more behaviors that could never be explained by a strictly particle-view of light. Jul 10, - The Ray Model uses ray diagrams to explain things like how lenses focus The wave model describes how light propagates much like how.
