Description : Distinguish between uniform rectilinear motion and nonuniform rectilinear motion.
Last Answer : Distinguish between uniform rectilinear motion and nonuniform rectilinear motion.
Description : For uniform acceleration in rectilinear motion which of the following is not correct?
Last Answer : For uniform acceleration in rectilinear motion which of the following is not correct? (A) ... displacement (D) Velocity-time graph is nonlinear
Description : When light enters a closed room through a small hole in the door, the image of an outside building appears as inverted on the opposite wall. This is because (a) The hole acts as a convex lens (b) ... the edges of the hole (c) Of rectilinear propagation of light (d) The hole acts as a concave lens
Last Answer : Ans:(b)
Description : A small hole in the window of a closed room forms an inverted image of outside building on the opposite wall of the room. This happens because (a) the rays of light suffer lateral inversion on entering the ... propagation of light (c) the hole acts as a convex lens (d) the hole acts as a prism
Description : A water tank appears shallower when it is viewed from top due to – (1) rectilinear propagation of light (2) reflection (3) total internal reflection (4) refraction
Last Answer : (4) refraction Explanation: This phenomenon is because of refraction of light. The lines of sight intersect at a higher position than where the actual rays originated. This causes the water to appear shallower than it really is.
Description : Formation of shadows can be explained by - (1) rectilinear propagation of light (2) reflection (3) refraction (4) total internal reflection
Last Answer : (1) rectilinear propagation of light Explanation: In this position, the head light will be at the principal focus so that the rays of light falling on the concave mirror will be rendered parallel
Last Answer : (4) refraction Explanation: This phenomenon is because of refraction of light. The lines of sight intersect at a higher position than where the actual rays originated. This causes the water to appear ... depth that the water appears to be when viewed from above is known as the apparent depth.
Last Answer : (1) rectilinear propagation of light Explanation: In this position, the head light will be at the principal focus so that the rays of light falling on the concave mirror will be rendered parallel.
Description : Eclipses occur due to which optical phenomena? (1) Reflection (2) Refraction (3) Rectilinear propagation (4) Diffraction
Last Answer : (3) Rectilinear propagation Explanation: An eclipse is an astronomical event that occurs when an astronomical object is temporarily obscured, either by passing into the shadow of another body or by having ... a wave property which states that waves propagate (move or spread out) in straight lines.

Last Answer : C) The differential equation in which both rectilinear and angular motions exit
Description : What is meant by coupled differential equation? a. The differential equation in which only rectilinear motions exit b. The differential equation in which only angular motions exit c. The differential equation in which both rectilinear and angular motions exit d. None of the above
Last Answer : c. The differential equation in which both rectilinear and angular motions exit
Description : A water tank appears shallower when it is viewed from top due to (1) rectilinear propagation of light (2) reflection (3) total internal reflection (4) refraction
Last Answer : refraction
Last Answer : Rectilinear propagation
