Question
1. Which of the following law(s) was/were used to come up with the Compton Shift equation of the wavelength of scattered photons?
a. conservation of momentum.
b.conservation of energy.
c. conservation of charge.
d. conservation of momentum and charge.
e. conservation of energy and momentum.
2. An electron jumps down from n = 12 state to the n = 2 state in a hydrogen atom. In which of the following series the wavelength of the photon appears?
a. Lyman
b. Balmer
c. Paschen
d. Brackett
e. All of these
f. choices are correct.
Explanation / Answer
1) e. conservation of energy and momentum.
by using law of conservation of energy and law of conservation of momentum, we derive equation for compton shift.
2) b. Balmer
from any value of n1 to n2 = 2,
all these wavelengths come under Balmer series.
