SATHEE: Atomic Structure Question 33

Atomic Structure Question 33

Question: If change in energy $(Δ E) = 3 \times 10^{- 8} J, h = 6.64 \times 10^{- 34} J - s$ and $c = 3 \times 10^{8}, m / s,$ then wavelength of the light is [CBSE PMT 2000]

Options:

A) $6.36 \times 10^{3} \AA$

B) $6.36 \times 10^{5} \AA$

C) $6.64 \times 10^{- 8} \AA$

D) $6.36 \times 10^{18} \AA$

Show Answer

Answer:

Correct Answer: C

Solution:

$Δ E = \frac{h c}{λ}$ or $λ = \frac{h c}{Δ E}$

$= \frac{6.64 \times 10^{- 34} \times 3 \times 10^{8}}{3 \times 10^{- 8}} = 6.64 \times 10^{- 8} \AA$
