Question

To vary the angle as well as the intensity of polarized light, ordinary unpolarized light is passed through one polarizer with its transmission axis vertical, and then a second polarizer is placed between the first polarizer and the insect. When the light leaving the second polarizer has half the intensity of the original unpolarized light, which statement is true about the two types of cells? (a) Only type H detects this light. (b) Only type V detects this light. (c) Both types detect this light, but type H detects lighter. (d) Both types detect this light, but type V detects more light

Step-by-Step Solution

Answer

Option (d) Both types detect this light, but type V detects more light is the correct option

Step1: Polarized light

Polarized light is that which is reflected or transmitted through a certain media so that all the vibrations in the light are restricted to a certain single plane

Step2: Explanation

Since we are given that the unpolarized light goes through one polarizer with the vertical axis. The light is polarised by this one and then passes through the sound polarizer and reduced to its half intensity. Hence the final polarised light is in the vertical direction, so the type V is the only type that gets detected by the light.
