   If  a wave has a wavelength of  1cm  it must  be a microwave

      Explanation
Microwave are  form of  electromagnetic radiation  with a wavelength  ranging  from   one   meter to  1 millimeter  and  a frequency   ranging  from  300 MHz  to 300  GHz. Therefore   the  wavelength  of 1cm  it must be a microwave since  1cm  is within the range.

Answer:

Option B

Explanation:

The wavelength of gamma rays is very low and is nearly equal to or less than 10 Pico meters.

Wavelengths of microwave are with in centimeters with maximum wavelength ranging up to 30 centimeters

Wavelength of Radio Waves ranges between 1 mm to 100 kilometers and the wavelength of Ray is equivalent to the wavelengths of the visible spectrum which lies between 400 and 780 nanometers

Hence, option B is correct
