Chapter 16: Problem 2301

A polariser is used for (A) produce polarised light (B) produce unpolarised light (C) produce unpolarised light (D) none of these

Short Answer

Expert verified
A polariser is used primarily to produce polarised light by allowing light waves of a specific polarization to pass through while blocking light waves of other polarizations. Hence, the correct answer is (A) produce polarised light.

Step by step solution

01

Understanding the role of a polariser

A polariser is an optical filter that allows light waves of a specific polarization to pass through while blocking light waves of other polarizations. It has the ability to transform unpolarised light into polarised light or to filter the polarisation of already polarised light.
02

Analyze the given options

(A) Produce polarised light: Polarisers are used to transform unpolarised light into polarised light. This is one of their main applications. (B) Produce unpolarised light: Polarisers cannot produce unpolarised light. They can only filter polarisations. (C) Produce unpolarised light: This option is the same as (B) and is also incorrect. (D) None of these: This option is incorrect because polarisers are known to produce polarised light.
03

Select the correct answer

Based on our analysis, the correct answer to this exercise is (A) produce polarised light.
