Question

A photon of frequency ν has a momentum associated with it. If c is the velocity of light, this momentum is –

• A. $\frac { h v } { c ^ { 2 } }$
• B. $\frac { \mathrm { h } v } { \mathrm { c } }$
• C. ν/c
• D. hνc

Answer 1

Answer: (B)

$\frac { \mathrm { h } v } { \mathrm { c } }$

Answer 2

E = mc² = hν

p = mc =
