14) What is the frequency of an xray with a wavelength of 2x10-10m? a) 1.5 x 1018hz b) 6.67x10-19hz c) 3x108hz d) 1.5hz

Question

Show calculations ! Thank you!

Answer 1

Frequency is the ration between speed of the X-rays (i.e., speed of light) and the wavelength.

f = c / λ = 3×10⁸ m/s / 2×10^-10 m = 1.5×10¹⁸ Hz
