CUET Ray Optics Previous Year Questions With Solutions

CUET Ray Optics PYQ With Solutions will help you to understand CUET important topics. By solving these, you can practice better, clear doubts, and boost confidence for exams. Let’s check the questions now.

Q1. In which medical instrument is the principle of Total Internal Reflection (TIR) directly used to transmit light/images?

(a) Telescope

(b) Microscope

(c) Endoscope

(d) Camera

Answer: (c) Endoscope

Solution:

An endoscope is a thin flexible tube that sends light into the body and brings images back to the observer. It uses optical fibers, which trap light by total internal reflection at the core–cladding boundary (core has higher refractive index). Each bounce keeps the light inside, so images travel long distances with minimal loss.

Q2. A spectrometer is primarily used to study which phenomenon?

(a) Reflection

(b) Refraction

(c) Dispersion

(d) Polarization

Answer: (c) Dispersion

Solution:

A spectrometer (with a prism or diffraction grating) separates polychromatic light into constituent wavelengths. This angular separation by wavelength is dispersion, allowing measurement of spectral lines and refractive indices.

Q3. In binoculars, Porro/roof prisms are inserted mainly to:

(a) Increase magnification.

(b) Invert an inverted image to erect.

(c) Disperse light into colors.

(d) Reduce chromatic aberration.

Answer: (b) Invert an inverted image to erect

Solution:

The objective lens produces an inverted image. Prism pairs inside binoculars flip the image to erect via multiple reflections. They also shorten the optical path while keeping the device compact, but the key reason is image erection.

Q4. Which mirror is used in vehicle headlights?

(a) Convex mirror

(b) Plane mirror

(c) Concave mirror

(d) Cylindrical mirror

Answer: (c) Concave mirror Solution

Solution:

A concave mirror converges parallel rays of light. In vehicle headlights, the bulb is placed at the focus of a concave mirror. This setup helps the light rays bounce off the mirror and become parallel. As a result, this creates a strong beam of light that effectively lights up the road ahead.

Q5. Myopia (near-sightedness) is corrected using:

(a) Convex lens

(b) Concave lens

(c) Cylindrical lens

(d) Prism only

Answer: (b) Concave lens

Solution:

In myopia, distant objects focus in front of the retina because the eye’s power is too high or eyeball is too long. A diverging (concave) lens reduces the effective power so that parallel rays from distant objects focus on the retina.

Q6. Which lens combination is commonly used in camera objectives to control aberrations?

(a) Single convex lens only

(b) Single concave lens only

(c) Compound lens: convex + concave elements

(d) No lens—just aperture

Answer: (c) Compound lens: convex + concave elements

Solution:

Real camera lenses consist of multi-elements. By combining converging and diverging elements (which is often made from different types of glasses) helps correct spherical and chromatic aberrations, improving sharpness across the frame.

Q7. A person sees distant objects clearly but struggles with near objects. This condition is:

(a) Myopia

(b) Hypermetropia

(c) Astigmatism

(d) Night blindness

Answer: (b) Hypermetropia

Solution:

In hypermetropia, the eye’s power is too low (or eyeball short), so near objects would focus behind the retina. A convex (converging) lens adds power, bringing the near image forward onto the retina.

Q8. The power of the eye lens increases when we focus on a nearby object because:

(a) Iris contracts

(b) Retina moves

(c) Ciliary muscles contract, making lens more convex

(d) Eyeball lengthens instantly

Answer: (c) Ciliary muscles contract, making lens more convex

Solution:

For near vision, accommodation occurs: ciliary muscles contract, zonular fibers relax, and the lens becomes more curved (shorter focal length), thus increasing optical power to focus close objects on the retina.

Q9. The formation of a mirage on an extremely hot road is mainly caused by:

(a) Reflection caused by the road surface.

(b) Diffraction of light around hot air.

(c) Atmospheric refraction caused by the temperature gradient.

(d) Dispersion of sunlight.

Answer: (c) Atmospheric refraction caused by the temperature gradient.

Solution:

Near a hot surface, air is hotter & less dense; higher layers are cooler and denser. Refractive index increases with density, so rays from the sky bend gradually away from the normal, curving upward. The observer receives these rays as if they came from a reflected image below the horizon, creating the illusion of water—this is a superior mirage effect from continuous refraction, not mirror reflection.

Q10. A concave mirror with a radius of curvature 20 cm comprises an image of the sun. The diameter of the sun subtends an angle of 1° as viewed from the Earth. The diameter of the image is in centimeters.

(a) 2π/9

(b) π/9

(c) 20

(d) π/18

Answer: (d) π/18

Solution:

The Sun is very far, so its rays are nearly parallel. A concave mirror forms the image at its focus. Using the small-angle formula, image size = focal length × angle in radians:

h = f.θ = 10. π/180 = π/18 cm

So, the diameter of the Sun’s image on the mirror is π/18 cm.
