Question

if energy of the electromagnetic wave 6.48*10power5j. calculate the total momentum of the wave (c=3*10power8m/s

Answer 1

HI

HERE IZ UR ANSWER.

Given,
U = Energy = 6.48 * 10^5 J
C = 3*10^8 m/s

P = U/C
= ( 6.48*10^5 )  / ( 3*10^8 )
= 2.16 * 10^-3 kgm/s

HOPE IT HELPS

Answer 2

Answer:

The total momentum of the wave is equal to 2.16×$10^{-3} \frac{kgm}{sec}$.

Explanation:

The energy of the electromagnetic wave is 6.48×$10^{5} J$.

By the equation,

$P=\frac{U}{C}$

P = Momentum of the electromagnetic wave

U = Energy of the electromagnetic wave

C = Speed of the electromagnetic wave

$P=\frac{U}{C}$

   = 6.48×$10^{5}$/3×$10^{8}$

   = 2.16×$10^{-3} \frac{kgm}{sec}$

So, the total momentum of the wave is equal to 2.16×$10^{-3} \frac{kgm}{sec}$.
