Arithmetic progression class 10 || Basic introduction

Due to a vertical temperature gradient in the atmosphere, the index of refraction varies. Suppose index of refraction varies as n=n_(0) sqrt(1+ay) , where n_(0) is the index of refraction at the surface and a=2.0xx10^(-6)m^(-1) . A person of height h=2.0 m stands on a level surface. Beyond what distance will he not see the runway?

Twinkling of stars is due to atmospheric refraction.' Explain this statement with the help of a diagram and state the reason why planets do not twinkle.

At what depth below the surface of water will pressure be equal to twice the atmospheric pressure ? The atmospheric pressure is 10N cm^(-2) , density of water is 10^(3)kg m^(-3) and g=9.8 ms^(-2) .
