Hint
To solve this question, recall the laws of refraction and analyze each ray in the figure to determine which ones satisfy the conditions.
Quick Oral Answer
The three rays that are obeying the laws of refraction and may be used for locating the position of image formed by a convex lens are 2, 3, and 4. This is because these rays satisfy the conditions of the laws of refraction, which state that the incident ray, the refracted ray, and the normal to the surface at the point of incidence all lie in the same plane.
Analysis & Explanation
This question requires the application of the laws of refraction to determine which rays are obeying the laws and can be used to locate the position of the image formed by a convex lens. The correct answer is option B, which corresponds to rays 2, 3, and 4.
Common Mistakes
- 1confusing the laws of reflection with the laws of refraction
- 2not analyzing each ray individually
Interesting Facts
The laws of refraction were first discovered by Snell in 1621.
Convex lenses are commonly used in optical instruments such as microscopes and telescopes.
