Atomic Structure Question 392
Question: Arrange the electromagnetic radiations a, b, c, d and e in increasing order of energy. Frequencies of a, b and c are $ 10^{15},10^{14} $ and $ ~10^{17} $ respectively whereas wavelength of d and e are 350 nm and 100 nm respectively-
Options:
A) a, b, c, d, e
B) a, b, d, e, c
C) a, d, b, e, c
D) b, a, d, e, c
Show Answer
Answer:
Correct Answer: D
Solution:
- $ E=hv $ and $ v=( \frac{c}{\lambda } ) $
$ v_{a}=10^{15},,v_{b}=10^{14},v_{c}=10^{17},v_{d}=0.85\times 10^{15} $ and $ v_{e}=3\times 10^{15}, $
