Correct Answer:
Wrong Answer:
Percentage: %
- A. Yes
- B. No
- C. It depends on the medium the light is traveling through
- D. It depends on the intensity of the light
Remarks:
Explanation:
Answer: A) Yes Explanation: Different colored light has different wavelengths and frequencies, which are responsible for their distinct colors.
- A. Refractive index
- B. Wavelength
- C. Frequency
- D. Amplitude
Remarks:
Explanation:
Answer: A) Refractive index
- A. Its component colours
- B. Different shapes
- C. Different sizes
- D. Different intensities
Remarks:
Explanation:
Answer: A) Its component colours Explanation: When a beam of white light or composite light is refracted through any transparent media such as glass or water, it is split into its component colours. This phenomenon is called as ‘dispersion of light’.
- A. Rayleigh scattering
- B. Mie scattering
- C. Tyndall scattering
- D. Raman scattering
Remarks:
Explanation:
Answer: C) Tyndall scattering Explanation: The scattering of light rays by colloidal particles in a colloidal solution is called Tyndall scattering.
- A. The scattering of light by the colloidal particles in a colloidal solution.
- B. The scattering of light by atmospheric gases in the lower portion of the atmosphere.
- C. The scattering of light by pollen, dust, smoke, and other particles in the atmosphere.
- D. The scattering of light by atmospheric gases in the upper portion of the atmosphere.
Remarks:
Explanation:
Answer: A) The scattering of light by the colloidal particles in a colloidal solution.Explanation: The Tyndall effect is the scattering of light by the colloidal particles in a colloidal solution. It occurs when light passes through a colloidal solution, and the particles in the solution scatter the light in all directions, making the path of the light visible.
- A. More
- B. Less
- C. Equally
- D. None of the above
Remarks:
Explanation:
the particles in the denser medium is tightly packed so the light can not freely travel as in rarer medium.So the velocity of light in denser medium is less
- A. The scattering of light by atmospheric gases in the upper portion of the atmosphere.
- B. The scattering of light by atmospheric gases in the lower portion of the atmosphere.
- C. The scattering of light by the colloidal particles in a colloidal solution
- D. The interaction of light with the particles of pure liquids or transparent solids, which leads to a change in wavelength or frequency
Remarks:
Explanation:
Answer: D) The interaction of light with the particles of pure liquids or transparent solids, which leads to a change in wavelength or frequency. Explanation: Raman scattering, also known as the Raman effect, is the interaction of light with the particles of pure liquids or transparent solids, which leads to a change in wavelength or frequency. When a parallel beam of monochromatic light passes through a gas, liquid, or transparent solid, a part of the light rays are scattered, and the scattered light contains some additional frequencies or wavelengths other than that of the incident frequency or wavelength.
- A. Convex lens
- B. Concave lens
- C. Plano-convex lens
- D. Plano-concave lens
Remarks:
Explanation:
Answer: A) Convex lens Explanation: Convex lenses are used in binoculars and cameras to focus the light and create a clear image.
- A. Convex lens
- B. Concave lens
- C. Cylindrical lens
- D. Spherical lens
Remarks:
Explanation:
Answer: C) Cylindrical lens Explanation: A cylindrical lens is used to correct astigmatism, which is an uneven curvature of the cornea that causes distorted vision.
- A. Light is a form of energy
- B. Light always travels along a straight line
- C. Light needs medium for its propagation
- D. None of the above
Remarks:
Explanation:
According to properties of light ,light doesn't require any medium for its propagation.It can travel through vaccum.
