Answers
Answer:
The right option is option D i.e clay.
The second one next to this is plastic.
Explanation:
We can make use of all of the other options suggested in the question to make a lens of clean a class.
However we cannot use clay while making a lens. This is somewhat out of the four options suitable. This is because clay will not allow any light to pass through it and hence this will be against the transparent nature so that light can pass freely.
Even plastic will not support reflection or refraction of light so we should not use plastic also.
Answer:
The correct answer of this question is option D,clay.
Explanation:
An optical lens should be always transparent ,in order to allow the light rays to pass through the lens.
And among the four options mentioned in the question,the clay is only substance which is completely opaque and that's why we cannot use clay to make optical lenses.
For this reason, option D is the correct answer of this question.
