Plane and convex mirrors, Physics

Assignment Help:

(a) You have studied that plane and convex mirrors produce virtual images of objects.

Can they generate real image under some circumstances? Explain.

(b) A virtual image we always say can't be caught on a screen. Yet when we 'see' a virtual image we are perceptibly bringing it on to the'screen' (i.e., the retina)of our eye. Is there a contradiction?

(c) A diver under water looks simplicitly at a fisher man standing on the bank of a lake. Would the fisher man look shorter or taller to the diver than what he actually is?

(d) Does the obvious depth of a tank of water change if viewed obliquely? If thus, does the apparent depth increase or decrease?

(e) The refractive index of diamond is much greater than that of ordinary glass. Is this fact of some use to a diamond cutter?

Answer

(a) Yes

Convex and Plane mirror scan produce real images as well. If the object is virtual that is if the light rays converging at a point behind a plane mirror or a convex mirror are reflected to a point on a screen placed in front of the mirror then a real image will be formed.

(b) No

A virtual image is produced when light rays diverge. The convex lens of the eye origins these divergent rays to converge at the retina. In this case the virtual image serves as an object for the lens to produce a real image.

(c)A diver is in the water and the fisher man is on land that is in air. Water is a denser medium than air it is given that the diver is screening the fisherman. This specifies that the light rays are travelling from a denser medium to a rarer medium.

Thus the refracted rays will move away from the normal. As a outcome the fisher man will appear to be taller.

(d)Yes; Decrease

The obvious depth of a tank of water changes when viewed obliquely. This is for the reason that light bends on travelling from one medium to another. The obvious depth of the tank when viewed obliquely is less than the near

(e)Yes

The refractive index of diamond (2.42) is additional than that of ordinary glass(1.5).The critical angle for diamond is less than that for glass. Diamond cutter uses a large angle of incidence to ensure that the light entering the diamond is totally reflected from its faces. This is the cause for the spark ling effect of a diamond.
