Answer: Ultraviolet
Step-by-step explanation:
The Electromagnetic spectrum involves gamma rays , X rays, ultra violet rays, visible rays, infrared rays, micro waves and radio waves which are arranged in order of increasing wavelength and decreasing frequency.
The wavelength range for gamma rays is less than 0.001 nm.
The wavelength range for ultraviolet rays is 1 nm to 400 nm.
The wavelength range for visible rays is 400 nm to 750 nm.
The wavelength range for infra red rays is 700 nm to 1000000 nm.
It can be seen from the graph that the most intense radiation for the star occurs near a wavelength of 200 nm , thus the most intense radiation occurs in ultraviolet band.
