A point object is placed at a distance of 20 cm from a glass slab, half immersed in water as shown in figure. The distance between two images when seen from the other side of the slab is `(mu_(g) = (3)/(2) and mu_(w) = (4)/(3))`

A point object is placed at a distance of 20 cm from a glass slab, H=18cm, half immersed in water as shown in figure. The distance between two images when seen from the other side of the slab is (mu_(g) = (3)/(2) and mu_(w) = (4)/(3))

A glass sphere of radius R=10cm is kept inside water. A ponit object O is placed at 20cm from A as shown in figure. Find the position and nature of the image when seen from other side of the sphere. Also draw the ray diagram. Given, mu_g=3//2 and mu_w=4//3

A point object is placed at a distance of 25cm from a convex lens. Its focal length is 22cm. A glass slab of refractive index 1.5 is inserted between the lens and the object, then the image is formed at infinity. Find the thickness of the glass slab (in cm).

An air bubble inside a glass slab (mu= 1.5) appears at 6 cm when viewed from one side and 4 cm when viewed from the opposite side. The thickness of the slab is

A biconvex lens of focal length 40 cm is placed in front of an object at a distance of 20 cm . Now a slab of refractive index 4/3 is placed somewhere in between the lens and the object. The shift in the image formed after the introduction of slab equals (thickness of the slab is 2 mm)
