Front

Which electromagnetic wave has a shorter wavelength: Visible Light or Infrared Light?

Back

Visible Light has a shorter wavelength than Infrared Light.

Front

Which electromagnetic wave has a longer wavelength: Radiowaves or Visible Light?

Back

Radiowaves have a longer wavelength than Visible Light.

Front

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

Back

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