Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is the EM Spectrum?

Back

The EM Spectrum, or Electromagnetic Spectrum, is the range of all types of electromagnetic radiation, including visible light, radio waves, and gamma rays.

Front

What are the main types of waves in the EM Spectrum?

Back

The main types of waves in the EM Spectrum include radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

Which part of the EM Spectrum can we see?

Back

The visible light portion of the EM Spectrum is the only part we can see.

Front

What happens to light when it hits a reflective surface?

Back

When light hits a reflective surface, it bounces back, a process known as reflection.

Front

What happens to light when it is absorbed by an object?

Back

When light is absorbed by an object, it is taken in and converted to other forms of energy, usually heat.

Front

What is wavelength?

Back

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

Front

How does wavelength relate to energy in waves?

Back

Waves with longer wavelengths have lower energy and lower frequency, while waves with shorter wavelengths have higher energy and higher frequency.

Front

What is frequency?

Back

Frequency is the number of waves that pass a point in one second, measured in hertz (Hz).

Front

What is an example of a wave that we cannot see?

Back

An example of a wave that we cannot see is infrared radiation.
