Answer 2

If According to indian almanac real sunrise of a day is 6:32 hour, then at the horizon sun will appear at ___(6:30_)___ hour.​

Explanation:

Refraction

The bending of light when it travels from one medium to another due to difference in the densities of medium .

Atmospheric refraction

The continuous bending of light when it travels through atmosphere because of  different layers of atmosphere with varying densities. that is : Upper ones on rarer and layers close to earth surface is denser.  

Due to this phenomenon sunrise  and sunset occurs 2 minutes  before the actual sunrise and sunset .

It is because of atmospheric refraction. When the Sun is slightly below the horizon, the light coming from it travels from less dense to more dense air and is refracted downwards. Thus, the Sun appears to be raised and can be seen 2 min before actual sunrise and 2 min after actual sunset.
