Chapter 18: Problem 110

For a concave mirror (A) virtual image is always larger in size. (B) real image is always smaller in size. (C) real image is always larger in size. (D) real image may be smaller or larger in size.

Short Answer

Expert verified
The correct answer is (D). A real image may be smaller or larger in size depending on the position of the object relative to the mirror.

Step by step solution

01

Analyze the Statements

Analyze all the given options (A), (B), (C), (D) one by one for their correctness. For a concave mirror, the size of the image can be larger, smaller, or equal to the size of the object, depending upon the position of the object.
02

Disprove A

\(A)\) states that a virtual image is always larger in size. This is not correct because a concave mirror produces a virtual image that is larger than the object only when the object is very close to the mirror. If the object is at the focus or beyond, a virtual image will not be formed.
03

Disprove B

\(B)\) states that a real image is always smaller in size. This statement is incorrect because a real image can be smaller, larger, or equal in size to the object, depending on the object's position relative to the mirror. The image is smaller when the object is beyond the center of curvature, and it is the same size at the center of curvature.
04

Disprove C

\(C)\) states that a real image is always larger in size. This is incorrect because a concave mirror forms a larger real image only when the object is between the mirror's pole and focus. The image is same size at the center of curvature; when the object is beyond the center of curvature, the image is diminished.
05

Substantiate D

The statement \(D)\) states that a real image may be smaller or larger in size. Considering that the size of a real image varies based on the relative position of the object, this is the correct option.

A microscope has an objective of focal length \(1.5 \mathrm{~cm}\) and an eye- piece of focal length \(2.5 \mathrm{~cm}\). If the distance between objective and eye-piece is \(25 \mathrm{~cm}\), what is the approximate value of magnification produced for relaxed eye? (A) 75 (B) 110 (C) 140 (D) 25

The refractive index of water is \(4 / 3\) and that of glass is \(5 / 3\). Then the critical angle for a ray of light entering in water from glass will be (A) \(\sin ^{-1}\left(\frac{4}{5}\right)\) (B) \(\sin ^{-1}\left(\frac{5}{4}\right)\) (C) \(\sin ^{-1}\left(\frac{20}{9}\right)\) (D) \(\sin ^{-1}\left(\frac{9}{20}\right)\)

Two convex lenses placed in contact form the image of a distant object at \(P\). If the lens \(B\) is moved to the right, the image will (A) move to the left. (B) move to the right. (C) remain at \(P\). (D) move either to the left or right, depending upon focal lengths of the lenses.

The box of a pin hole camera, of length \(L\), has a hole of radius \(a\). It is assumed that when the hole is illuminated by a parallel beam of light of wavelength the spread of the spot (obtained on the opposite wall of the camera) is the sum of its geometrical spread and the spread due to diffraction. The spot would then have its minimum size (say \(b_{\min }\) ) when \([2016]\) (A) \(a=\sqrt{\lambda L}\) and \(b_{\min }=\left(\frac{2 \lambda^{2}}{L}\right)\) (B) \(a=\sqrt{\lambda L}\) and \(b_{\min }=\sqrt{4 \lambda L}\) (C) \(a=\frac{\lambda^{2}}{L}\) and \(b_{\min }=\sqrt{4 \lambda L}\) (D) \(a=\frac{\lambda^{2}}{L}\) and \(b_{\min }=\left(\frac{2 \lambda^{2}}{L}\right)\)
