Is the formula "Real depth/Apparent depth = mu." valid if viewed from a position quite away from the normal ?

When refraction occurs from denser to……….., then (mu_2)/(mu_1) = …………. .

Identify the statements are True of False. a. The equation (mu_(2))/(v)-(mu_(1))/(u)=(mu_(12)-mu_(1))/(R) is applicabel to a plane surface for R=oo . h. In the above equation, mu_(1) is medium in which the object is placed and mu_(2) is the medium in which the image is formed. c. In the figure shown, the real image of object O is formed at a distance 5R in the medium. d. In figure, the image of an object O place on the center face of the sphere is formed at infinity,. e. In fig , the image of an object O placed on the opposite face of the sphere is foremd at infinity.

What is the relation between the refractive indices mu,mu_(1) and mu_(2) if the behaviour of light rays is shown in Figure.

Path of ray of light passing through three liquids of refractive indices mu_1,mu_2,mu_3 is as shown in Fig. Which liquid has the smallest index of refraction ? .

Figure shows figure three transparent medi of refractive indices mu_1, mu_2 and mu_3 . A point object O is placed in the medium mu_2 . If the entire medium on the right of the spherical surface has refractive index mu_1 , the image forms at O. If this entire medium has refractive index mu_2 the image form at O''. In the situation shown

The reciprocalof ((mu_(2)-mu_(1))/(R)) gives the value of
