  1. An excellent comparison of the wave and particle theories involves the differences that occur when light is reflected from a smooth, specular surface, such as a mirror. This interactive tutorial explores how particles and waves behave when reflected from a smooth surface. Start Tutorial ».

  2. Light is called an 'electromagnetic wave' for historical reasons* in the following sense: It turned out that the effects of visible light and other radiation can be calculated using Maxwell's equations, which are also used to model the behaviour of electrically charged particles. This was an instant of a successful unification and it hasn't ...

  3. Apr 10, 2022 · Describe the relationship between wavelength, frequency, and speed of light. Discuss the particle model of light and the definition of photon. Explain how and why the amount of light we see from an object depends upon its distance.

  4. May 24, 2024 · We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.

  5. If light is a particle, then why does it refract when travelling from one medium to another? And if light is a wave, then why does it dislodge electrons ? But all behavior of light can be explained by combining the two models: light behaves like particles and light behaves like waves.

  6. Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference . Like all electromagnetic waves, light can travel through a vacuum.
