Infrared rays have a shorter wavelength than Question 11 options: X-rays. ultraviolet rays. radio waves. gamma rays.

Answer : Infrared rays have a shorter wavelength than radio waves.

Explanation:

The wavelength of Infrared rays is 700 nm - 1 mm

The wavelength of X - rays is 0.01 nm - 10 nm

The wavelength of UV rays is 10 nm - 400 nm

The wavelength of radio waves is 1 meter - 100,000 km

The wavelength of gamma rays is less than 0.01 nm

So, from the above data it is clear that the wavelength of the infrared rays have a wavelength shorter than the radio waves.

Hence, the correct option is (C) " radio waves ".

Infrared rays have a shorter wavelength than radio waves.
