Two plane mirrors M1 and M2 are inclined to each other at an angle of 60 degrees as shown in figure. If a ray is incident at an angle of y degrees with normal on mirror M1 then what will be the value of x in degrees?

Q. In the given figure two plane mirrors M1 and M2 are inclined at an angle of θ with each other. If the reflected ray suffers a net deviation of 200 degrees then what will be the value of (θ+X) in degrees ?

Q.

The plane mirrors $M_1$ and $M_2$ are inclined to each other such that a ray of light incident on mirror $M_1$ and parallel to the mirror $M_2$ is reflected from mirror $M_2$ parallel to the mirror $M_1$. The angle between the two mirror is (in degrees)

Q. Two plane mirror are inclined to one another at an angle of ${60}^o$. A ray is incident on mirror $M_1$ at an angle $i$. The reflected ray from mirror $M_2$ is parallel to mirror $M_1$as shown in figure. The angle of incidence $i$ is:

Q. Two plane mirrors $M_1$ and $M_2$ are inclined to each other at ${70}^{\circ }.$ A ray incident on the mirror $M_1$ at an angle $\theta$ falls on $M_2$ and is then reflected parallel to M, for

Q. Two plane mirrors are inclined to each other at an angle of ${55}^{\circ }$ as shown in figure. A ray of light PO incident at some angle i on the mirror $M_1$ falls after reflection from it, on the other mirror $M_2$ from which it gets reflected along a direction parallel to the plane mirror $M_1.$ Find the value of i.
