Electromagnetic Spectrum Test Study Guide

What is the height of a wave from its resting point?

Amplitude

All waves transfer____ from one place to another

Energy

What is the number of waves that pass a point in one second?

Frequency

Which wave property ,measures how many waves pass a point in one second

Frequency

These high-energy waves are given off by radioactive materials.

Gamma

Increasing the amplitude of a wave, _________ the wave's energy.

Increases

The energy of waves _______ as the wavelength gets shorter.

Increases

These waves make water molecules vibrate and warm up.

Microwaves

How do the terms light, radiation, and waves relate to one another?

Radiation refers to electromagnetic waves, which are one specific type of wave. Light refers to the portion of the electromagnetic spectrum that is in or near the visible light spectrum. So light is both a wave and a type of radiation.

These waves are used to send signals, including WiFi and text messages.

Radio

____waves are used to send signals because they can travel over very long distances and pass through buildings

Radio

Why are X-Rays used to produce images of broken bones?

They can pass through our body, but get absorbed by bones

A black light uses___ radiation to make some objects glow

Ultra Violet

These waves from the sun cause sunburn.

Ultraviolet

What causes waves?

Vibrations in matter cause waves. (Students are likely to be familiar with vibrations causing sound waves and with disturbances in water causing water waves. They are not likely to know that the movement of charged particles causes electromagnetic waves.)

What are some examples of waves in everyday life?

Water waves, sound waves, light waves, and waves in a string or slinky are examples of waves in everyday life.

What is a repeating pattern that can transfer energy?

Wave

Each of the different colors that make up white light has a different

Wavelength

What is the distance from the peak of one wave to the next peak?

Wavelength

Which property of electromagnetic waves must go down as the frequency goes up?

Wavelength

Any object above absolute zero gives off_____ radiation, which can be detected by a thermal imaging camera

infrared

How does a prism separate white light into the different colors that compose it?

it is bent, or refracted, by the angles and plane faces of the prism and each wavelength of light is refracted by a slightly different amount.
