Answer:
a) the light is close to normal therefore the reference incidence of medium 1 is less than medium n2 where the ray is transmitted.
b) The ray is far from normal in this case the refractive index of medium 1 is greater than index of medium 2
Explanation:
The expression for the angle of refraction is
n₁ sin θ₁ = n₂ sin θ₂
refractive index n₁ is for incident light and n₂ is for transmitted light.
We have two cases
a) the light is close to normal therefore the reference incidence of medium 1 is less than medium n2 where the ray is transmitted.
b) The ray is far from normal in this case the refractive index of medium 1 is greater than index of medium 2
Answer:
15.8 N
Explanation:
The component in a given direction is the magnitude of the applied force, multiplied by the cosine of the angle between its application and the direction of interest.
The horizontal component is ...
(20 N)cos(38°) ≈ 15.8 N
Answer:
Mass is the inertia of object. Momentum is the inertia in motion.
Explanation:
Mass:- Mass is the measurement of inertia. Mass of an object depends upon number of atoms present in a object. its unit is kg. mass is the inertia of object.
Momentum:- It is the product of Mass And velocity.
Momentum is given by the formula P = m × v
Momentum is the inertia in motion. it increases with increase of mass , velocity or both increases.
Momentum unit is .
