Two plane mirrors are inclined at 70°. A rayincident on one mirror...
From fig. 40° + θ = 90° ∴ θ = 90° – 40° = 50°

° to each other. A ray of light is incident on one of the mirrors at an angle of 40° to the mirror surface. Draw a diagram to show the path of the ray after two reflections.
To draw the diagram, follow these steps:
1. Draw the two mirrors, inclined at 70° to each other. Label them as mirror 1 and mirror 2.
2. Draw the incident ray, which is coming in at an angle of 40° to mirror 1. Label it as ray 1.
3. Draw the reflected ray from mirror 1. To do this, draw a line perpendicular to the mirror surface at the point of incidence of ray 1. Then draw the reflected ray at the same angle as the incident ray, but on the other side of the perpendicular line. Label this as ray 2.
4. Draw the second reflection of ray 2 on mirror 2. To do this, draw a line perpendicular to mirror 2 at the point where ray 2 intersects it. Then draw the reflected ray at the same angle as ray 2, but on the other side of the perpendicular line. Label this as ray 3.
5. The path of the ray after two reflections is the final position of ray 3. Draw this line to complete the diagram.
The final diagram should show two mirrors inclined at 70° to each other, with an incident ray coming in at an angle of 40° to mirror 1. The diagram should also show the path of the ray after two reflections, with the final position of the ray labeled as ray 3.
