Awave is incident on the surface of a mirror at an angle of 41° with the normal. what can you say about its angle of reflection?

a.)it is less than the angle of incidence.

b.)it is equal to the angle of incidence.

c.)it is greater than the angle of incidence.

d.)it is zero, as it reflects along the normal

b.)It is equal to the angle of incidence.

Explanation:

As we know that 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.)It is equal to the angle of incidence.

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

so it must be

fgravity=10x10=100n case 1

fgravity=30x20=600n case 2

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
