Question 4 • Physics

Which idea did Isaac Newton’s experiments with light support?

Answer
A
Light is produced by the interaction of magnetic and electric fields.
B
Light is made of particles because it travels only in a straight path.
C
Light is a wave because it has properties that are similar to radio waves.
D
Light is a wave because it bends around barriers.

Explanation

Newton’s experiments with prisms showed that white light can be separated into different colors and recombined. He interpreted light as being made of tiny particles, or corpuscles, that travel in straight lines. This supports choice C, the idea that light is made of particles because it travels only in a straight path.
