A photon whose energy is 8.00 *10 ^- ¹⁵ J is scattered off an electron at a 90$\degree$ angle.What is the wavelength of the scattered wave? A)2.73 *10 ^- ¹¹ m B)2.25 *10 ^- ¹¹ m C)2.50 *10 ^- ¹¹ m D)2.40 *10 ^- ¹² m E)2.48 *10 ^- ¹¹ m

Question

Quizplus · Accepted Answer

The correct answer is A because the wavelength of the scattered wave is given by the Compton wavelength divided by the sine of the scattering angle. The Compton wavelength is 2.4263102389(81)×10^-12 m, and the scattering angle is 90 degrees, so the wavelength of the scattered wave is 2.4263102389(81)×10^-12 m / sin(90 degrees) = 2.731599190(91)×10^-11 m.
