Answer:
1. The bending of light as it passes from one medium to another is called refraction. The angle and wavelength at which the light enters a substance and the density of that substance determine how much the light is refracted. The bending occurs because light travels more slowly in a denser medium.
2.The changing of a light ray's direction (loosely called bending) when it passes through variations in matter is called refraction. The index of refraction is n=c/v, where v is the speed of light in the material, c is the speed of light in vacuum, and n is the index of refraction.
3. Newton and the color spectrum: dispersive refraction
While he was not the first to demonstrate that a prism produces a spectrum of colored light from incident white light, he showed that a second prism could recombine the colors to create white light again.
4. optical prism
An optical prism is a transparent optical element with flat, polished surfaces that refract light.
5.Complete step-by-step answer: The case of multiple reflections is shown above. Multiple reflection of light is the reflection of light back and forth through reflecting surfaces several times. When the reflection of a reflected light ray on another object is mirrored again, it is called multiple reflections.
6.When an object moves back and forth, it is called a vibration.
7.
8.Temperature is the degree of hotness or coldness of an object.
9.electric circuit
A closed loop through which current can flow is called an electric circuit. In homes in the U.S., most electric circuits have a voltage of 120 volts. The amount of current (amps) a circuit carries depends on the number and power of electrical devices connected to the circuit.
10.An automatic voltage regulator (AVR) is an electronic device that maintains a constant voltage level to electrical equipment on the same load. The AVR regulates voltage variations to deliver constant, reliable power supply.
