Light Waves and Sound Waves Review

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, which includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

Which electromagnetic wave has the lowest energy?

Back

Microwave.

Front

What is the order of waves on the electromagnetic spectrum from longest wavelength to shortest?

Back

Radio, Microwave, Infrared, Visible, Ultraviolet, X-ray, Gamma.

Front

What happens to light when it passes from air into water?

Back

Light bends when it passes through water, causing objects to appear displaced or broken.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, changing its speed.

Front

What is reflection?

Back

Reflection is the bouncing back of light when it hits a surface.

Front

What is frequency in relation to waves?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz). Higher frequency means more waves in a given time.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive peaks or troughs in a wave.

Front

How does the speed of light change in different mediums?

Back

The speed of light is fastest in a vacuum and slows down when it passes through materials like water or glass.

Front

What is the relationship between wavelength and frequency?

Back

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