Topic: Refraction of Light Why does a pencil look bent in water? The water molecule is so common that it is wise to just memorize that water is a BENT molecule. Hey. It is safe!! 3 Answers. It is because of refraction of light. Observing Objects in Water. To do that, let me just draw a simplified version of that picture. Hence, the pencil appears to bent at the water surface. Hey!! Before doing more examples with Snell's Law, which essentially amount to some math problems, what I want to do is get an intuitive understanding for why this straw looks bent in this picture right over here. Stop crying!! Lv 6. An object seen in the water will usually appear to be at a different depth than it actually is, due to the refraction of light rays as they travel from the water into the air. Ratto. 1 decade ago. Still have questions? That was a very cool magic trick!! Because when light enters the water and reflects off the pencil, the reflected light rays strike the water surface and is refracted at an angle dependent on the refractive index. Explain with the help of a diagram, why a pencil partly immersed in water appears to be bent at the water surface. As you sight at the portion of the pencil that was submerged in the water, light travels from water to air (or from water to glass to air). The oxygen has 6 valence electrons and thus needs 2 more electrons from 2 hydrogen atoms to complete its octet. Thus, the immersed portion of pencil in water appears as CB'. An example of bent molecular geometry that results from tetrahedral electron pair geometry is H 2 O. The reason you see a bent pencil is because when you place it in the water, ripples form and the surface of the water experiences waves as opposed to a surface at rest. As a result, the image of the pencil appears to be broken. That was a very cool magic trick. When stick is immersed partly in water then light coming from stick refracts at the surface of water due to change in density of medium. 0 0. Topic: Refraction of Light Why does a pencil look bent in water? Answer Save. This tutorial explores how fish, observed from the bank of a pond or lake, appear to be closer to the surface than they really are. AayUoo. Relevance. It looks bent to the refraction of the water and light. But do you know why your magic wand appeared bent in water? You are seeing the reflective magnification of the water, thereby enlarging and 'moving' the pencil. This light ray changes medium and subsequently undergoes refraction. Water: Chime in new window. Why does pencil immersed obliquely in water appear bent ans short?explain with ray diagram 2 See answers harshkumargoluku harshkumargoluku When a pencil is obliquely dipped in water , the ray of light travelling from pencil to observer travel from denser medium to … Stop crying. The path of any light beam is deviated (bent) as it goes from one medium to another such as going from air to glass. Look!! The refracted rays appear to come from point B'. 0 0. why does a pencil look bent in water? Now check this out!! So … 1 decade ago. Your magic wand is not bent or broken!! Now check this out. Wow. Asked by Topperlearning User | 26th Aug, 2014, 09:43: AM Expert Answer: Rays of light from the tip (B) of the pencil bend away from the normal as they go from water to air. Wow!!
