Question

In the electromagnetic spectrum, ν1​, ν2​, and ν3​ respectively denote the frequencies of microwaves, ultraviolet waves, and gamma-rays. We can conclude that:

• A. $\quad \nu_1 > \nu_2 > \nu_3 \\\\$
• B. $\quad \nu_1 < \nu_2 < \nu_3 \\\\$
• C. $\quad \nu_2 > \nu_1 > \nu_3 \\\\$
• D. $\quad \nu_3 < \nu_1 < \nu_2$

Answer 1

Answer: (B)

$\quad \nu_1 < \nu_2 < \nu_3 \\\\$

Answer 2

In the electromagnetic spectrum, the frequency increases as we move from mi crowaves to ultraviolet waves to gamma rays. Therefore, the correct order of frequencies is:
$\quad \nu_1 < \nu_2 < \nu_3 \\\\$
where:- ν1 corresponds to microwaves (lower frequency), ν2 corresponds to ultraviolet waves (medium frequency), ν3 corresponds to gamma rays (highest frequency).
Thus, the correct relationship is:
$\quad \nu_1 < \nu_2 < \nu_3 \\\\$
which corresponds to Option (2).
