Question

Draw the ray diagram of a bending of a stick partly dipped in water obliquely​

Answer 1

$\huge{\tt{\red{}\green{A}\purple{N}\pink{S}\blue{W}\orange{E}\red{R}}}$

Due to refraction from denser medium to rarer medium, the light coming from stick's end refracts away from normal as shown in figure

and thus when refracted ray extended backward then it meets sticks end at some height above to actual depth of end.

that's why the sticks appears bent and shorter inside water.

Answer 2

Answer:

(a) A stick partly immersed in water appears to be bent. Draw a ray diagram to show the bending of the stick when placed in water and viewed obliquely from above.

(b) A ray of monochromatic light is incident from air on a glass slab :

1. Draw a labelled ray diagram showing the change in the path of the ray till it emerges from the glass slab.

2. Name the two rays that are parallel to each other. (Hi) Mark the lateral displacement in your diagram.

(c) An erect, magnified and virtual image is formed, when an object is placed between the optical centre and principal focus of a lens.

1. Name the lens.

2. Draw a ray diagram to show the formation of the image with the above stated characteristics.
