gamma rays have an approximate wavelength of 1.0x10^-13 meters. what is the approximate energy of a gamma-ray?

E = 19.89 × 10⁻¹³ J

Explanation:

Given data:

Wavelength of gamma ray= 1.0× 10⁻¹³ m

Energy of gamma ray = ?

Solution:

Formula:

E = h c/λ

h = plancks constant  = 6.63× 10⁻³⁴ js

c = speed of light = 3 ×10⁸ m/s

by putting values,

E = 6.63× 10⁻³⁴ js × 3 ×10⁸ m/s /1.0× 10⁻¹³ m

E = 19.89 × 10⁻²⁶ J.m/ 1.0× 10⁻¹³ m

E = 19.89 × 10⁻¹³ J
