Question

which are characteristics of the speed of light? check all that apply. the speed of light is the speed all waves travel. the speed of light is the speed electromagnetic waves travel. the speed of light is 3.0 x 10^8 m/s in space. the speed of light is the same in all matter. the speed of higher frequency light slows down more than lower frequency light in matter.

Explanation:

Light is an electromagnetic wave. In a vacuum (space), the speed of light is approximately $3.0\times10^{8}$ m/s. Different types of waves have different speeds. The speed of light varies in different media (not the same in all matter), and higher - frequency light slows down more than lower - frequency light in matter due to dispersion.

Answer:

The speed of light is the speed electromagnetic waves travel.
The speed of light is 3.0 x 10⁸ m/s in space.
The speed of higher frequency light slows down more than lower frequency light in matter.
