Current Question (ID: 20673)

Question:

$\text{Arrange the following in the ascending order of wavelength:}$ $\text{A. Gamma rays } (\lambda_1)$ $\text{B. x-rays } (\lambda_2)$ $\text{C. Infrared waves } (\lambda_3)$ $\text{D. Microwaves } (\lambda_4)$ $\text{Choose the most appropriate answer from the options given below.}$

Options:

1. $\lambda_4 < \lambda_3 < \lambda_1 < \lambda_2$
2. $\lambda_2 < \lambda_1 < \lambda_4 < \lambda_3$
3. $\lambda_4 < \lambda_3 < \lambda_2 < \lambda_1$
4. $\lambda_1 < \lambda_2 < \lambda_3 < \lambda_4$

Solution:

$\text{The correct order of increasing wavelength is:}$ $\lambda_1 < \lambda_2 < \lambda_3 < \lambda_4$ $\text{This corresponds to option 4.}$
