Answer:
The frequency , speed and wavelength of an electromagnetic wave are related by the formula
Speed = frequency x wavelength
frequency = speed / wavelength
substituting the values
frequency = 3 x #10 ^8# m /s / 1 x #10^15# m
= 3 x #10^-7# /s
A shorter electromagnetic wave is hotter.
A shorter electromagnetic wave produce heat hotter than ultraviolet rays. Because it produces both gamma rays and ultraviolet rays that makes it hotter that the heat of the sun.
It depends on what that "certain amount" is.
The answer is Hertz (Hz) named in honor of the German scientist Heinrich Hertz, who first conclusively proved the existence of electromagnetic waves.
