Here light ray strikes to interface at an angle of 45 degree and then refracts into other medium such that it will bend towards boundary.
So here the angle of incidence will be less than the angle of refraction as light moves towards the boundary after refraction which mean it will bend away from the normal
here it can be said that medium 2 will be rarer then medium 1
So here the possible options are
1. Water
Air
2. Diamond
Air
So in above two options medium 1 is denser and medium 2 is rarer

Answer:
Publishing results of research projects in peer-reviewed journals enables the scientific and medical community to evaluate the findings themselves. It also provides instructions so that other researchers can repeat the experiment or build on it to verify and confirm the results.
The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges.
Answer:
Explanation:
The force due to gravity on earth's surface on mass 
is:
Where,
F = GMm/R2
F = Gravitational Force
G = Gravitational Constant
M = Earth's Mass
m = mass of body
R = Earth's radius
The acceleration is F/m:
For a planet with 0.11M and 0.53R:
Hence gravity on Mar's surface is 3.8377
