Answer:
There is no significant energy loss in the total internal reflection and the reflected ray has entire light wave energy so that a brighter image is formed, but some energy in the plane mirror is absorbed inside and thus energy loss.
Explanation:
Advantages
- If the light is reflected from the total prism, the entire light is completely reflected internally. But only about 90% of the incident light is reflected from the mirror of the plane. Consequently, reflected light intensity is more in the prism than light reflected in the plane mirror.
- There are no more reflections in the prism as in the plane mirror in its entirety.
- In the case of a total prism as in the plane mirror, the image is not reversed laterally.
- It requires no silvering, one of the benefits.
