Explain why a pencil partly immersed in water, appears displace at the interface of the water?? As you sight at the portion of the pencil that is submerged in the water, light travels from water to air (or from water to glass to air). Answer is B.The light reaching you from the portion of the pencil inside water seems to come from a different direction, compared to the part above water. Refraction in a water surface.

Explain with the help of a diagram, why a pencil partly immersed in water appears to be bent at the water surface. Assertion: When a pencil is partly immersed in water and held obliquely to the surface, the pencil appears to bend at the water surface This makes the pencil appear to be displaced at the interface.It appears that when traveling obliquely from one medium to another, the direction of propagation of light in the second medium changes. • Explanation of Solution. Name the type of mirror used in the following situations: As light enters water at an angle, it bends away from its original path, and this makes the image look bent. Figure shows a straight stick AO whose lower portion BO is immersed in water. The light reaching out from the portion of the pencil inside water seems to come from a different direction, compared to the part above water due to refraction of light. (b) Name the phenomenon due to which a pencil partly immersed in water and held obliquely appears to be bent at the water surface. Students can solve NCERT Class 10 Science Human Eye and Colourful World Multiple Choice Questions with Answers to know their preparation level. Similarly, when a pencil is partly immersed in water in a glass tumbler, it appears to be displaced from its original position at the surface. Draw a ray diagram to show the bending of the stick. The phenomenon that makes the pencil appear to be bent is called refraction. asked Feb 24, 2019 in Physics by Aksat (69.3k points) (a) A stick partly immersed in water appears to be bent.

When a pencil is partly immersed in water and held in a slanting position, it appears to be bent at the boundary separating water and air. This phenomenon is called refraction. The pencil appears bent and slightly larger because it appears closer. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. • The refraction causes an apparent shift in the position of the part of the pencil within the water. It appears to be displaced at the interface of air and water. ← Prev Question Next Question →. This happens because the rays appear to come from P’ (which is the virtual image of the tip P of the stick) due to refraction from denser medium (water) to rarer medium (air) at the surface separating two media.
