Light is a transverse, electromagnetic wave that can be seen by a typical human. Wavelengths in the range of 400–700 nm are normally thought of as light.
Light Waves: Problem Set. Problem 1: In 1957, the U.S. Naval Research Laboratory conducted the first ever radar measurements of the distance from the Earth to the moon.
We have 10 ready-to-use problem sets on the topic of Light Waves. These problem sets focus on the use of wave principles and equations to solve physics word problems associated with light speed, frequency, wavelength, illuminance, the Doppler shift, and two-point source interference.
Examples of light include radio and infrared waves, visible light, ultraviolet radiation, and X-rays. Interestingly, not all light phenomena can be explained by Maxwell’s theory. Experiments performed early in the twentieth century showed that light has corpuscular, or particle-like, properties.
Dec 7, 2022 · Light has the properties of waves. Like ocean waves, light waves have crests and troughs. The distance between one crest and the next, which is the same as the distance between one trough and the next, is called the wavelength .
Problems on Light as a wave. Problem : Find an expression for the angular frequency of a wave in terms of the wavelength and phase velocity. The most general form of a harmonic wave is given by ψ = A cos [k(x - vt)], where v is the phase velocity and k is the wave number. Expanding this we have ψ = A cos (kx - kvt).

IIT JEE Study Material. Properties of Light. Light is a form of energy that causes the sensation of vision. Different theories on the nature of light were proposed on the basis of the fact that energy can be transferred from one point to another, either by particle motion or by wave motion.
