Question

Which of the following radiations has largest energy?
12. = 30 nm
2) 2. = 300 pm
3) v = 3x1012 ,-
1) y = 3x10105-1​

Answer 1

Answer:

2) 2. =300 pm

Explanation:

this is the correct answer of this question

Answer 2

Answer:

2) λ = 300 pm

Explanation:

as, E=hc/λ

so, E is inversely proportional to λ

thus as λ decreases E increases

300pm < 30nm as per the options which are given in λ

thus option B is the right answer.
