Hint: Direction of the light changes when passing through different medium with reflection or refraction. All mirrors use the concept of reflection of light and that makes vision possible.
Complete step by step solution: Firstly, in the side mirror of a car, we use a convex mirror which reflects light and enables the driver of the car to have peripheral vision and see the things behind.
Let’s discuss periscope now, it is an instrument that allows vision around, over or through an obstacle and where normal direct line of vision is not possible. These are usually used in the army, navy etc. It uses two plane mirrors and uses the reflection of light for image formation. It is still used in submarines as well as tanks.
And we know that all mirrors use reflection of light and that is how we see images in mirrors. We see the reflected image, which is accurate but reversed form. The reflected light from a mirror bounces in the same angle as it hit, but in the opposite direction.
It is interesting to know that objects either emit or reflect light in order for us to see them. For example, the sun emits light and we see it while we see a ball because of the light being reflected from it.
Final answer is option (D).
Note: Reflection of light is the bouncing back of light after hitting a surface. And that is how we see things around us. The light changes its direction while entering from one medium to another medium. Vision is possible because light reflected from objects enters our eyes.
