Mcq on spherical mirrors physics class 10 -with-answers

Question 1. No matter how far you stand from mirror, your image appears erect. The mirror is likely to be.......

---

A) Plane
B) Concave
C) Convex
D) Either Plane or Convex

Answer: D) Either Plane or Convex
Explanation:-
Plane mirrors and convex mirrors will always produce an upright image (erect image).

Question 2. Name a mirror that can give an erect and enlarged image of an object.

---

A) Concave
B) convex
C) Both
D) None of these

Answer : A) Concave
Explanation:-
Concave mirrors form both real and virtual images. When any concave mirror is placed very close to the object, a virtual and magnified image is obtained and if we increase the distance between the object and the mirror, the size of the image reduces and real images are formed.

Question 3. Name a mirror that forms both real and virtual images of an object

---

A) Concave
B) Convex
C) Both
D) None of these

Answer : A) Concave
Explanation:-
Concave mirrors form both real and virtual images. When any concave mirror is placed very close to the object, a virtual and magnified image is obtained and if we increase the distance between the object and the mirror, the size of the image reduces and real images are formed.

Question 4.Mirror having a curved reflecting surface are called as:

---

A) Plane mirror
B) Spherical mirrors
C) Simple mirror
D) None of the above

Answer: B) Spherical mirrors
Explanation:-
Spherical mirror is a mirror, whose reflecting surface is part of a hollow sphere of glass. The spherical mirrors are of two types: 1. concave mirrors and 2. convex mirrors.

Question 5. Spherical mirror with reflecting surface curved inwards is called ……………

---

A) Convex mirror.
B) Concave mirror
C) Curved mirror
D) None of the above

Answer: B) Concave mirror
Explanation:-
A concave mirror is a spherical mirror in which the reflection of light takes place at surface,which is curved inwards.

Question 6. Pole lies on the surface of ……………….

---

A) Spherical mirrors
B) Simple mirror
C) Plane mirror
D) None of the above

Answer: A) Spherical mirrors
Explanation:-
The Pole of a spherical mirror (convex or concave) is the center of the reflecting surface of the spherical mirror. It lies on the surface of the spherical mirror.

Question 7. The centre of a sphere of which the reflecting surface of a spherical mirror is a part is called ………………..

---

A) Pole
B) Centre of curvature
C) The radius of Curvature
D) Aperture

Answer: B) Centre of curvature
Explanation:-
Centre of curvature is not a part of the spherical mirror rather it lies outside the mirror)

Question 8. Centre of curvature is not a part of the spherical mirror rather it lies ………….. the mirror

---

A) Boundary
B) Inside
C) Outside
D) None of the above

Answer: C) Outside
Explanation:-
Centre of curvature is not a part of the spherical mirror rather it lies outside the mirror)

Question 9. In concave mirror, centre of curvature lies in ………… of the reflecting surface

---

A) Boundary
B) Inside
C) Outside
D) Front

Answer: D) Front
Explanation:-
The centre of curvature of a concave mirror lies in front of it.

Question 10. The radius of a sphere; of which the reflecting surface of a spherical mirror is a part; is called the………….

---

A) Centre of curvature
B) The radius of Curvature
C) Pole
D) Aperture

Answer: B) The radius of Curvature
Explanation:-
The radius of the sphere of which the reflecting surface of a spherical mirror forms a part, is called the radius of curvature of the mirror.

Question 11. The diameter of the reflecting surface of a spherical mirror is called …………….

---

A) Centre of curvature
B) The radius of Curvature
C) Pole
D) Aperture

Answer: D) Aperture
Explanation:-
The diameter of the reflecting surface of a spherical mirror is called its aperture.

Question 12. The imaginary line passing through the centre of curvature and pole of a spherical mirror is called the ………….

---

A) Principal Axis
B) The radius of Curvature
C) Pole
D) Aperture

Answer: A) Principal Axis
Explanation:-
The imaginary line passing through the centre of curvature and pole of a spherical mirror is called the Principal Axis .

Question 13. The point on the principal axis at which parallel rays; coming from infinity; coverage after reflection is called the ……………..

---

A) Principal Focus
B) The radius of Curvature
C) Pole
D) Aperture

Answer: A) Principal Focus
Explanation:-
The point on the principal axis at which parallel rays; coming from infinity; coverage after reflection is called the Principal Focus.

Question 14. The image formed by a concave mirror is observed to be virtual, erect and larger than the object. Where should be the position of the object ?

---

A) Between the principal focus and the centre of curvature.
B) At the centre of curvature.
C) Beyond the centre of curvature.
D) Between the pole of the mirror and its principal focus.

Answer: D) Between the pole of the mirror and its principal focus.
Explanation:-
.

Question 15. Which of the following best describes image formation by a plane mirror?

---

A) A real image is formed in front of mirror.
B) A real image is formed behind the mirror.
C) A virtual image is formed in front of mirror.
D) A virtual image is formed behind the mirror.

Answer: D) A virtual image is formed behind the mirror.
Explanation:-
Images formed by plane mirrors are virtual, upright, left-right reversed, the same distance from the mirror as the object's distance, and the same size as the object.so,A virtual image is formed behind the mirror best describes image formation by a plane mirror.
