EM Waves Review

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another.

Front

What color will you see when you look through an orange filter?

Back

You will see orange.

Front

What is reflection?

Back

Reflection is the bouncing back of waves off an object.

Front

Which color of light has the longest wavelength?

Back

Red light has the longest wavelength.

Front

What color will you see when looking at a beach ball through a red and green filter?

Back

You will see black, as the red filter transmits red light and the green filter absorbs it.

Front

What is the relationship between wavelength and frequency in electromagnetic waves?

Back

Wavelength and frequency are inversely related; as wavelength increases, frequency decreases.

Front

What happens to light when it passes through a prism?

Back

Light is refracted and dispersed into its component colors.

Front

What is the visible spectrum?

Back

The visible spectrum is the range of wavelengths of light that can be seen by the human eye, typically from about 380 nm to 750 nm.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (or about 186,282 miles per second).

Front

How does a filter affect the color of light?

Back

A filter allows certain wavelengths of light to pass through while absorbing others, thus changing the color of the transmitted light.
