Light Review

Scientists know that electromagnetic radiation travels as an electromagnetic (a)   .

Scientists have evidence that electromagnetic radiation behaves like a stream of (a)   .

English physicist Thomas Young showed evidence that light behaves like a wave with his double slit experiment. It showed alternating light and dark bands, indicating constructive and destructive interference. (a)  

The emission of electrons from a metal when light strikes the metal is called

In 1905, Albert Einstein proposed that light, and all electromagnetic radiation, consists of packets of energy. These packets of electromagnetic radiation are called (a)  

Blue light has a lower frequency than red light. (a)  

Photons of blue light have more energy than photons of red light. (a)  

The (a)   of light decreases as photons travel farther from the source.

(a)   is the rate at which a wave's energy flows through a given unit of area. You can think of it as "brightness".

Which has a higher frequency: gamma rays or microwaves? (a)
