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

The Correct Option is B

The electromagnetic spectrum is ordered by frequency (and inversely by wavelength). The order from lowest to highest frequency is: 

1. Radio waves
2. Microwaves
3. Infrared
4. Visible light
5. Ultraviolet
6. X-rays
7. Gamma rays

Therefore, we can arrange the given frequencies in ascending order:

\( \nu_1 < \nu_2 < \nu_3 \\ \text{microwaves} < \text{ultraviolet} < \text{gamma-rays} \)

Answer: \( \nu_1 < \nu_2 < \nu_3 \)

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).
