Explanation:
Answer:
For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity.
Answer:
Explanation:
The intensity of polarised light after polarization through angle θ
I = I₀ cos²θ
Here θ = 23 for first polariser
Intensity after first polarisation
= I₀ cos²23 = .846 I₀
For second polariser θ = 90 - 23 = 67 degree
Intensity after second polarisation
= .846 I₀ cos²67 = .13 I₀ .
The water has an irregular surface so if the light rays fall on top then it will reflect oppositely or in some cases may refract, so the fish will seem a bit smaller or further or closer in anyway, example if u put a straw in water it looks bent but is it ? nope. So the main reason is that it refracts which makes the accuracy lesser which make it difficult.
