Gamma-ray bursters are objects in the universe that emit pulses of gamma rays with high energies. the frequency of the most energetic bursts has been measured at around 3.0 × 1021 hz. the speed of light is 3 × 108 m/s. what is the wavelength of these gamma rays? answer in units of m

Wavelength and frequency are related and they are indirectly related The higher the frequency of a light, the shorter the wavelength would be. The constant of proportionality of this relation is the speed of light. We calculate as follows:
wavelength = speed of light / frequency
wavelength = 3x10^8 / 3.0x10^21
wavelength = 1x10^-13 m

The correct answer is c. hope this
