what is total reflecting prism ? State one purpose for which it is used.
Answers
Answer:
A prism having an angle of 90
0
between its two refracting surfaces and the other two angles each equal to 45
0
, is called a total reflecting prism. The light incident normally on any of its faces, suffers total internal reflection inside the prism.
Due of this behavior, a total reflecting prism is used for the following three actions.
(a) To deviate a ray of light through 90
0
(b) To deviate a ray of light through 180
0
, and
(c) To erect the inverted image without producing deviation in its path.
In the below figure, it is an erecting prism which is used to erect the inverted image without producing deviation in its path
Answer:
A total reflecting prism is a prism that reflects the light that falls normally on its faces, if angle of incidence is more than the critical angle (critical angle of glass is 420), then total internal reflection takes place. ... It deviates light falling on any of its faces through 900
(a) To deviate a ray of light through 90°
(b) To deviate a ray of light through 180°
(c) To erect the inverted image without producing deviation in its path.
In the below figure, it is an erecting prism which is used to erect the inverted image without producing deviation in its path.
