Question

The wave length at which maximum absorption of radiation takes place is known as

• A. β_max
• B. α_max
• C. λ_max
• D. A_max

Answer 1

The Correct Option is C

To solve the given question, we need to understand the concept of wavelength in the context of radiation absorption. The wavelength at which maximum absorption of radiation occurs is crucial in fields like spectroscopy. Let's break down the details:

The term associated with the wavelength at which a substance absorbs the most radiation is generally termed as the peak wavelength. In scientific notation, this is often denoted as \lambda_{\text{max}}.

Here's an explanation of the options provided:

1. β_max: This term is not standardly used in the context of absorption maxima and thus is incorrect.
2. α_max: This generally indicates a coefficient or other factor and not a wavelength, so it is incorrect.
3. λ_max: \lambda_{\text{max}} represents the wavelength at which maximum absorption occurs, which is the correct and standard term used in disciplines such as physics and chemistry, especially in spectroscopy.
4. A_max: This term could stand for maximum absorbance in a specific context but does not represent a wavelength, thus making it incorrect for this question.

Conclusion: The correct choice is λ_max, as it is widely recognized and used to denote the wavelength at which maximum absorption takes place.

This concept is fundamental in spectroscopic analysis, where understanding the \lambda_{\text{max}} is essential for characterizing materials based on their absorption spectra.
