FAQs on Optics Mock Test for JEE Main 2025-26: Practice, Analyze, Excel
1. What is optics and why is it important in physics?
Optics is the branch of physics that deals with the study of light, its behavior, and its interactions with different materials. It is important because it helps us to understand phenomena such as reflection, refraction, dispersion, and image formation by lenses and mirrors, which are essential in science, technology, and daily life.
2. What are the main differences between ray optics and wave optics?
Ray optics (or geometric optics) considers light as a straight-line ray and explains phenomena like reflection and refraction. Wave optics treats light as a wave and explains effects like interference, diffraction, and polarisation. Ray optics is applicable when the wavelength of light is much smaller than the objects it interacts with, while wave optics is needed to explain phenomena involving the wave nature of light.
3. What is Snell's Law in optics?
Snell's Law states the relationship between the angles of incidence and refraction when light passes from one medium to another with different refractive indices. Mathematically, it is given by n1 sinθ1 = n2 sinθ2, where n1 and n2 are the refractive indices of the two media and θ1 and θ2 are the respective angles with the normal.
4. How does a concave lens form images?
Concave lenses are diverging lenses that form images by spreading outgoing rays. The images formed are always virtual, erect, and diminished and appear on the same side of the lens as the object. Image formation can be understood using ray diagrams and the lens formula.
5. Explain the phenomenon of total internal reflection.
Total internal reflection occurs when a ray of light travels from a denser medium to a rarer medium at an angle greater than the critical angle. Instead of refracting out, the light reflects entirely back into the denser medium. This principle is used in optical fibers and certain devices like prisms.
6. What is meant by dispersion of light?
Dispersion of light is the process by which a beam of white light splits into its constituent colors when passing through a prism or similar medium. It occurs because different wavelengths of light have different speeds in the medium, leading to varied angles of refraction for each color.
7. How do you distinguish between real and virtual images in optics?
Real images are formed when light rays actually converge at a point and can be captured on a screen. Virtual images are formed when rays only appear to diverge from a point and cannot be projected onto a screen. Examples include images formed by a concave mirror (real) versus a plane mirror (virtual).
8. What is interference of light and how is it observed?
Interference of light is the phenomenon where two or more coherent light waves superpose to produce regions of increased or decreased intensity (constructive and destructive interference). It is observed in Young's double slit experiment, producing alternating bright and dark fringes on a screen.
9. What are the applications of optical fibers?
Optical fibers use the principle of total internal reflection to transmit light signals over long distances. Key applications include:
• Telecommunications (high-speed internet and data transfer)
• Medical imaging (endoscopy)
• Sensors and illumination in various industries
10. What are the SI units of focal length and refractive index?
Focal length is measured in metres (m) in the SI system. Refractive index is a ratio and, therefore, has no units.
11. How is the magnification produced by a lens calculated?
Magnification by a lens is the ratio of the height of the image to the height of the object.
Formula: Magnification (m) = hi / ho = v/u, where hi is the image height, ho is the object height, v is image distance, and u is object distance. It describes how much larger or smaller the image is compared to the object.
12. What is the lens formula and how is it used?
The lens formula relates the object distance (u), image distance (v), and focal length (f) of a lens:
1/f = 1/v – 1/u. This equation helps to determine the position and size of the image formed by a lens in ray optics problems.
