Front

Which electromagnetic waves have the longest wavelength?

Back

Radio waves have the longest wavelength in the electromagnetic spectrum.

Front

Which electromagnetic waves have the shortest wavelength?

Back

Gamma rays have the shortest wavelength in the electromagnetic spectrum.

Front

What color of visible light has the shortest wavelength?

Back

Violet light has the shortest wavelength among visible colors.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

All electromagnetic waves travel at the same speed in a vacuum, which is approximately 299,792 kilometers per second (the speed of light).

Front

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

Back

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

Front

What type of electromagnetic wave is used in microwave ovens?

Back

Microwaves are the type of electromagnetic wave used in microwave ovens.

Front

What is the primary use of X-rays in medicine?

Back

X-rays are primarily used for imaging to view the inside of the body, such as bones and teeth.

Front

What is ultraviolet radiation commonly associated with?

Back

Ultraviolet radiation is commonly associated with sun exposure and can cause skin damage.
