Directions : In the following questions, A statement of Assertion (A)...
Gamma rays are electromagnetic waves having the smallest wavelength. So, the assertion is true.
Relation between wavelength and frequency is ν = c/λ.
c is the velocity of light and same for all electromagnetic waves. For Gamma rays wavelength being smallest, frequency will be highest. So, the reason is false.
Directions : In the following questions, A statement of Assertion (A)...
Assertion: Gamma rays are electromagnetic waves having the smallest wavelength.
Reason: Gamma rays are having the lowest frequency.
Explanation:
Gamma rays are a form of electromagnetic radiation, just like visible light, radio waves, and X-rays. They are characterized by their high energy and high frequency.
Assertion (A): Gamma rays are electromagnetic waves having the smallest wavelength.
Gamma rays have the smallest wavelength among the electromagnetic spectrum. The electromagnetic spectrum is a range of different wavelengths or frequencies of electromagnetic radiation. Gamma rays have wavelengths shorter than X-rays, ultraviolet (UV) rays, visible light, infrared (IR) rays, microwaves, and radio waves. Therefore, Assertion (A) is true.
Reason (R): Gamma rays are having the lowest frequency.
The reason provided is incorrect. Gamma rays actually have the highest frequency among the electromagnetic spectrum. Frequency is the number of wave cycles that occur in one second. Gamma rays have a frequency higher than X-rays, UV rays, visible light, IR rays, microwaves, and radio waves. Therefore, Reason (R) is false.
Conclusion:
The Assertion (A) is true, as gamma rays have the smallest wavelength. However, the Reason (R) is false because gamma rays have the highest frequency, not the lowest frequency. Hence, option C is the correct answer.
