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. 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. 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 at an angle $80$ degrees. A Ray of light is incident on one of the Mirrors. The ray after two reflection will undergo total deviation of:

Q. Two plane mirrors are inclined to each other at an angle $\theta$. A ray of light is reflected first at one mirror and then at the other. The total deviation of the ray is

Q. Two plane mirrors $M_1$ and $M_2$ are inclined at angle $\theta$ as shown in the figure. A ray of light l, which is parallel to $M_1$ strikes $M_2$ and after two reflections, the ray 2 becomes parallel to $M_2$. The angle $\theta$ is
