WebWorksheet -Class X, Chapter-10, Light (2/2: Refraction of Light) 1. A student determine the focal length of a device ‘X’ by focusing the image of a distant object on a screen placed 20 cm from the device on the same side as the object. The device ‘X’ is a) concave lens of focal length 10 cm b) convex lens of focal length 20 cm WebCLASS 10 PHYSICS WORKSHEET REFRACTIVE INDEX NUMERICALS 1. The refractive index of medium ‘X’ with respect to medium ‘Y’ is 2/3 and refractive index of medium ‘Y’ with respect to medium ‘Z’ is 4/3. Find the refractive index of medium ‘Z’ with respect to medium ‘X’. 2. The refractive index of water with respect to air is 4/3.
Web13 jul. 2024 · Answer: R = +32 cm. Therefore, f = R/2 = +32/2 = +16 cm. Thus, focal length of the convex mirror = +16 cm. Question 6. A concave mirror produces three times magnified (enlarged) real image of an object placed at 10 cm in front of it. Where is the image located ? Answer: m – -3, But m = -v/u, so v = 3u u = -10 cm v = 3 (-10 cm) =-30 cm WebLight – Reflection And Refraction Class 10 Science Extra Questions with Answers. 1. Explain why a ray of light passing through the centre of curvature of a concave mirror, gets reflected along the same path. Answer: The ray passing through the centre of curvature incident to the mirror along its normal so ∠i= ∠r = 0.
