![]() ![]() One consequence of diffraction is that sharp shadows are not produced. Diffraction takes place with sound with electromagnetic radiation, such as light, X-rays, and gamma rays and with very small moving particles such as atoms, neutrons, and electrons, which show wavelike properties. Please note that others may also have edited the contents of this article. diffraction, the spreading of waves around obstacles. One of the most important wave-like behaviors of light is reflection. On this page we will describe some of the behaviors of light as a wave including reflection, refraction, and diffraction. Physics 231 What is Light The main author of this article is Bredas, Jean-Luc Light has the unique property that it can be described in physics as both a wave and as a stream of particles called photons. N_1 sin \ \theta_1 = n_2 sin \ \theta_2\,\! External Links \nu\,\! is the frequency in hertzĢ\pi \ \frac \,\! 892 69K views 1 year ago Waves such as light and sound waves can bend, slow down, and speed up. Frequency is the number of occurrences of a repeating event per unit time.The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency.Ĭ= \lambda \nu \equiv \lambda_0 \nu\,\! \lambda_0\,\! is the wavelength in a vacuum. Very smooth surfaces such as mirrors reflect almost all incident light. The distance between two crests or troughs is the wavelength. Reflection Reflection is when incident light (incoming light) hits an object and bounces off. You can also consider the propagation of the wave in space or propagation in time. You can look at the propagation of the light as electric field and magnetic field propagating perpendicular to each other. ![]()
