Question

Which of the following have highest wave length n1=2, n1=3, n1=4 ,n1=n5

Answer 1

n₁ = 2

Step - by - step Explanation: Since we know that highest energy level will produce light with lowest wavelength.

→ Energy ∝ Frequency

→ Energy ∝ 1/Wavelength

Hemce, in order to get highest wave length we need lowest energy level & for highest energy to get lowest wave length. Hence your answer is n₁ = 2
