Answer:
Niels Bohr
Explanation:
Niel’s Bohr described the atomic model. He in his model showed that an atom is a small positively charged nucleus. Around the positively charged nucleus, electrons orbit in separate orbits.
The electrons in the outermost shell are responsible for the properties associated with an element.
The electrons at different shells have different energy. When an electron jumps from a shell of higher energy to a shell of lower energy, energy is released.

Explanation:
UV rays and X-rays are electromagnetic waves (do not require material medium for transmission). They are part of the electromagnetic spectrum and travel with the speed of light (3×10^8 m/s). In this case i believe the answer is C, X-rays have a higher frequency compared to UV rays.
