NCERT Solutions for Class 7 Science Chapter 11 Light Question and Answers

Question 1: Fill in the blanks:

(a) A _______ image cannot be formed on a screen.
(b) A _______ mirror is commonly used in vehicles for rear-view.
(c) A _______ lens always forms a virtual and smaller image.

(d) A _______ mirror can produce both real and virtual images.

Answer:

(a) virtual
(b) convex
(c) concave
(d) concave

Question 2: Name any five English alphabets that look the same in a mirror. Explain why.

Answer: Letters like A, H, I, M, O appear the same in a mirror because they are symmetrical along the vertical axis. That means their left and right halves are mirror images of each other, so when viewed in a mirror, they look unchanged.

Question 3: What is a real image? Give one example where it is formed.

Answer: A real image is formed when light rays actually meet after reflection or refraction. It can be shown on a screen.
Example: A concave mirror forms a real image of a candle placed beyond its focus.

Question 4: If a car moves backward at 3 m/s, how fast will the image in its plane rear-view mirror appear to move closer?

Answer: The image will appear to approach at 6 m/s, because the image moves backward the same distance as the object in the opposite direction, effectively doubling the rate.

Question 5: Match Column I with Column II.

Answer:

(a) → (iv)

(b) → (v)

(c) → (i), (iii)

(d) → (ii)

(e) → (ii)

Question 6: Write any three properties of the image formed by a plane mirror.

Answer: The image is upright.
It matches the size of the object.
The image is laterally inverted, meaning left and right are switched.

Question 7: What’s the difference between a convex lens and a concave lens?

Answer: Shape: A convex lens is thicker in the center, while a concave lens is thinner in the center.

Image Formation: A convex lens can create both real and virtual images, whereas a concave lens only produces virtual, upright, and smaller images.

Question 8: Can you give an example of a practical use for both a concave mirror and a convex mirror?

Answer: Concave mirror: It’s used in vehicle headlights to concentrate light into a focused beam.

Convex mirror: It’s commonly used as a rear-view mirror in cars to provide a wider field of view.

Question 9: Which type of lens is typically used to correct short-sightedness, and why?

Answer: A concave lens is used for short-sightedness because it spreads out light rays, allowing them to focus correctly on the retina.

Question 10: Which mirror consistently creates a virtual and smaller image, regardless of the object's position?

Answer: A convex mirror always produces a virtual, upright, and reduced image, no matter how far away the object is.

Question 11: Choose the correct answer: A real, inverted, and enlarged image can be formed by a –

(i) convex mirror
(ii) plane mirror
(iii) concave mirror
(iv) concave lens

Answer:
(iii) concave mirror

If you’re standing 2 meters in front of a plane mirror, how far away is your image from you? Can you explain?

Answer: Your image will actually be 4 meters away from you. It’s 2 meters behind the mirror and another 2 meters from you to the mirror, so when you add it all up, it’s 2 + 2 = 4 meters.
