Question

Wavelengths assigned to gamma rays, infra-red rays, UV rays and microwaves are \(\lambda_1\),\(\lambda_2\) , \(\lambda_3\) & \(\lambda_4\) respectively. Then :

(1) \(\lambda_1\) < \(\lambda_2\) < \(\lambda_3\) < \(\lambda_4\)

(2 )\(\lambda_1\) < \(\lambda_3\) < \(\lambda_2\) < \(\lambda_4\)

(3) \(\lambda_1\) > \(\lambda_2\)> \(\lambda_3\) > \(\lambda_4\)

(4) \(\lambda_2\) < \(\lambda_3\) < \(\lambda_1\) < \(\lambda_4\)

Answer 1

Correct Option is (2) λ₁ < λ₃ < λ₂ < λ₄
