Question

Choose all the answers that apply.

a) Light is created by vibrations in electric and magnetic fields.

b) Light travels in longitudinal waves.

c) Light slows down when traveling through dense substances.

d) Light does not require a medium.

e) Light can create heat when absorbed.

Answer 1

Light is created by vibrations in electric and magnetic fields and travels as a transverse wave. It does not require a medium to propagate, and light can create heat when absorbed.

Step-by-step explanation:

Light is created by vibrations in electric and magnetic fields and travels as a transverse wave. It does not require a medium to propagate, unlike sound waves which are mechanical waves and need a medium to travel through. Light can create heat when absorbed by an object. However, light does not slow down when traveling through dense substances.
