C) microwaves
D)visible light

Answer:

A) X-rays

Step-by-step explanation:

Ultraviolet rays have a frequency range of 10¹⁵ Hz to 10¹⁷ Hz.

X-rays have a frequency range of 10¹⁷ Hz to 10²⁰ Hz, so they have a higher frequency than UV waves.

B) is wrong. The frequency range of infrared light is 10¹³ Hz to 4 × 10¹⁴ Hz.

C) is wrong. The frequency range of microwaves is 3 ×10¹¹ Hz to 10¹³ Hz.

D) is wrong. The frequency range of microwaves is 4 ×10¹⁴ Hz to 7.5 × 10¹⁴ Hz.

The X-rays has a frequency greater than ultraviolet waves.  

• The range of all the kinds of electromagnetic radiation is known as the electromagnetic spectrum.  

• The types of the electromagnetic waves, which makes up the electromagnetic spectrum are the visible light, microwaves, infrared light, UV rays, X-rays, and gamma rays.  

• The energy of the waves is directly proportional to its frequency and inversely proportional to their wavelengths.  

• The radiowaves exhibits the photons with least energies, followed by microwaves, infrared rays, visible, UV rays, X-rays, and the most energetic of all the waves is the gamma rays.  

• The wavelengths of the UV rays is smaller than infrared waves, microwaves, and visible light, however, it is greater than X-rays and gamma rays.  

• Thus, the frequencies of UV rays is more than the infrared waves, microwaves, and visible light, but is lesser than the frequencies of X-rays and gamma rays.  

Thus, of the mentioned options, X-rays will possess greater frequency than UV rays.
