a. 4.24 MeV

b. 6.37 MeV

c. 2.12 MeV

d. 5.30 MeV

e. 3.18 MeV

What is the energy of a photon that has a wavelength of 41.0 nm?

a. 24.2 eVeV

b. 27.2 eVeV

c. 33.3 eVeV

d. 21.2 eVeV

e. 30.2 eVeV

Answer 1

For Q1. Answer is 5.30 MeV

For Q2. Answer is 30.2 eV

Explanation is given below :

Q = 1209.982873 u- 4.0026033 u – 205.97446534 7/93105). 8 = 5.40676 MeV -2 KitK2 = 8

kit2k1 = 5.40676 105K1 = 5.40676 : K1=5.30 MeV 103 Aus 103

2 dz4inm 2418109m E=HC = (6.6264034) (3x108) 418169 E = 4.85x1018J An ev E=30.2 er 1
