Electromagnetic Spectrum and Light Waves

Front

What is the speed of light?

Back

c = 3.0 x 10^8 m/s

Front

What is the definition of frequency?

Back

The number of waves passing a given point in a measured period of time.

Front

Why do we still see stars in the night sky even if they may have died millions of years ago?

Back

Because the light from that star is still travelling to Earth.

Front

What are the shortest light waves within the visible light range?

Back

Violet rays.

Front

What are the longest light waves within the visible light range?

Back

Red waves.

Front

What is the electromagnetic spectrum?

Back

The range of all types of electromagnetic radiation, including visible light, radio waves, and X-rays.

Front

What is wavelength?

Back

The distance between corresponding points on a wave.

Front

What is the relationship between frequency and wavelength?

Back

As frequency increases, wavelength decreases, and vice versa.

Front

What type of waves are visible light waves?

Back

Electromagnetic waves.

Front
