Question

In these diagrams, which one represents the correct path of rays?
(a) (I)
(b) (II)
(c) (III)
(b) (IV)​

Answer 1

Answer:

d) (|V)

Explanation:

D is the correct option because the rays will be going on the same direction and it will not turn to any direction ,so the rays travel in the straight line so the diagram 4 is the correct picture of Ray

I HOPE IT WAS HELPFUL TO ,IF YES THEN MARK THIS AS BRAIN LIST.

THANK YOU!!!!!!!

Answer 2

Figure (i) has the correct path of rays, and the reasons are given below -

• The path of ray for the figure first indicates that the light diverges from the path slightly, due to the refractive index of the prism. The speed of light in the prism changes therefore, the path changes.
• The path of the ray will not change drastically which is indicated as in figures second and third. So these two paths are wrong.
• For the figure fourth, the path or ray is seen unchanged, and this can not occur. Due to the change in the refractive index of the prism, the speed of light in the prism changes, hence the path change.
• So out of all the paths, the first figure stands out correct.
