Back

Gamma rays.

Front

What color of visible light has the shortest wavelength?

Back

Violet.

Front

How does the hazard level of electromagnetic waves change with increasing frequency?

Back

Energy increases, wavelength decreases; it becomes more hazardous.

Front

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

Back

As frequency increases, wavelength decreases.

Front

Which EM waves can cause sunburn?

Back

Ultraviolet rays.

Front

What is the order of the EM spectrum from lowest to highest frequency?

Back

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