Question

Which of the following electromagnetic radiations has the smallest wavelength?

• A. Ultraviolet rays
• B. X-rays
• C. \( \gamma \)-rays
• D. Microwaves

Hint:

The electromagnetic spectrum has a range of wavelengths. The higher the energy, the smaller the wavelength (e.g., \( \gamma \)-rays have the smallest wavelength).

Answer 1

The Correct Option is C

Step 1: Understand the relationship between wavelength and radiation type.
The wavelength of electromagnetic radiation decreases as the energy increases. The order of wavelengths from smallest to largest is: \( \gamma \)-rays, X-rays, ultraviolet rays, microwaves.
Step 2: Conclusion.
The smallest wavelength corresponds to \( \gamma \)-rays. Final Answer: \[ \boxed{\gamma \, \text{rays}} \]
