'B' is the correct choice.

BUT ... the angle of incidence is not the angle between the light ray
and the mirror.  It's the angle between the light ray and the NORMAL
to the mirror.  The 'normal' is the line that's perpendicular to the mirror.

Answer:

B. The angle the light ray makes as it strikes the surface.

Explanation:

Angle of the incidence is the angle that incident light ray will make with the normal to the surface at which light will strike. The surface is reflecting surface and here it follow the law of reflection

As per law of reflection of light angle of incidence with respect to the normal must be equal to the angle of reflection with normal in other direction.

So we can say that

angle of incidence = angle of reflection

so here we can say that the correct answer would be

B. The angle the light ray makes as it strikes the surface.

so the light ray will reflect at the same angle as that of angle of incidence given in it

so it must be

\theta_i = \theta_r

What is dark energy?
olga2289 [7]

Explanation:

Dark Energy. Dark Energy is a hypothetical form of energy that exerts a negative, repulsive pressure, behaving like the opposite of gravity. It has been hypothesised to account for the observational properties of distant type Ia supernovae, which show the universe going through an accelerated period of expansion

What does it mean tha velocity is vector quantity
Wewaii [24]
It means that velocity not only has a size, but it also has a direction.

Some other vector quantities are force and acceleration.
They have sizes and directions.
 
Temperature, cost, and weight are quantities with only size and no direction.
Those are called "scalar" quantities.

What do you mean by population size explain​
torisob [31]
Population size is the actual number of individuals in a population. Population density is a measurement of population size per unit area, i.e., population size divided by total land area. Abundance refers to the relative representation of a species in a particular ecosystem.
