The question asks to identify the law that describes the reflection of light. We need to recall the fundamental laws associated with light phenomena and general physics to determine the correct option.
Correct Option: D) The Law of Reflection describes how light bounces off a surface. It states that the angle of incidence is equal to the angle of reflection, and that the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane.
The question asks to identify the phenomenon explained by the refraction of light. We need to understand the definition of refraction and then evaluate each option based on this understanding.
C) Bending of light when passing from air to glass
This option directly describes the phenomenon of refraction, where light changes direction as it crosses the boundary between two media of different optical densities (air and glass).
The question asks about the type of lens used to correct hyperopia (farsightedness). To answer this, we need to understand what hyperopia is and how different types of lenses affect light rays.
A) Convex lens — A convex lens converges light rays, effectively shortening the focal length of the eye system and allowing the image to form directly on the retina for nearby objects. Therefore, it is used to correct hyperopia.
The question asks to identify the true statement about convex mirrors. We need to recall the image formation properties of convex mirrors and compare them with the given options.
Correct Option: B) They always form virtual images
The question asks to identify the phenomenon where light waves cancel each other out due to their phase difference. We need to recall the definitions of the given options in the context of wave optics.
C) Interference is the phenomenon where two or more waves superimpose to form a resultant wave of greater, lower, or the same amplitude. When waves are out of phase by an odd multiple of \(\pi\), they undergo destructive interference, leading to cancellation.
Which of the following colors is a primary color of light?
The question asks to identify a primary color of light from the given options. Understanding the concept of primary colors of light is crucial here.
Correct Option: A) Red is one of the three primary colors of light (Red, Green, Blue).
