Answer:

Gamma rays

Explanation:

The wavelength (λ) of electromagnetic waves is related to the frequency (ν) as follows:

λ = c/ν

where c = speed of light

ν = frequency

Given:

c = 2.998*10⁸ m/s

ν = 3*10¹⁹ Hz = 3*10¹⁹ s-1

Therefore: λ = 2.998*10⁸ m/s/ 3*10¹⁹ s-1 = 1.0 *10⁻⁸ m = 10 nm

A wavelength of 10 nm falls in the gamma region of the electromagnetic spectrum

Answer:-

A gamma rays

Explanation

Wavelength = speed of light / frequency

= (2.998 x 10^8 m/s)/ (3 x 10^19 Hz)

= 0.9993*10^-11 m

which is less than the threshold for X rays 10^-11 m.

Hence waves are gamma.
