Answer:
The true statement is d.
Explanation:
Nuclear fusion is the process in which two lighter nuclei are combined to form one heavy nucleus along with the huge amount of energy. This reaction takes place in the Sun.
frequency's unit is Hz which mean cycles per second
given frequency * wavelength = speed of wave
speed of light = 3x10^8 m/s
wavelength = 680nm = 680x10^-9 m
frequency * 680x10^-9 m = 3x10^8 m/s
frequency = 3x10^8 / 680x10^-9
= 4.41x10^14 Hz
= 441x10^12 Hz
= 441 THz
which is the frequency for red light
