Lab 26 Reflection And Refraction Of Light Answers

Light source flat mirror two aluminum supports for the mirror square glass plate pins ruler protractor cork.

Lab 26 reflection and refraction of light answers. The angle of refraction is the angle between the normal and the refracted ray in order to figure out whether light is speeding up or slowing down you need to compare the direction the light ray bends. Refraction we will learn that the angle of the ray when transmitted through the material changes and depends on the speed of light in the two materials. Refraction of light lab answers. To be able to understand the behavior of light when it reflects from an optical surface reflection and when it passes from one optical medium to another refraction.

This laboratory was designed to investigate the behaviour of light as it travels through a less dense into a denser medium. The law of reflection was known to the ancient greeks who made measurements that supported this law. Physics lab online simulation light reflection refraction critical angle spectrum electricity and light unit 6 ta name. Reflection takes place on the surface of an object and refraction occurs when light passes through an object.

Why do fish look larger in the water. The law of reflection states that on reflection from a smooth surface the angle of the reflected ray is equal to the angle of the incident ray. Light rays change direction when they reflect off a surface move from one transparent medium into another or travel through a medium whose composition is continuously changing. The conditions for total internal reflection to occur are.

Lab 6 optics introduction geometric optics is one of the oldest branches of physics dealing with the laws of reflection and refraction. Note that we may miss your response if it does not stand out re load the file in word or pdf format in canvas before the due date. Light must be travelling in the more refractive medium. Why do you use a laser in this lab rather than a light bulb.

Write your answers in blue. If a light ray bends towards the normal line this bending towards the normal means that the speed of light has decreased. Answer the following questions as you work through the lab. This lab uses the remote lab platform from phet interactive simulations at university of colorado boulder under the cc by 4 0 license.

You may need to support the mirror with clothespins or paperclips. Some of these are. If you wanted to use a light bulb what would you have to do to the light bulb. Place a blank piece of paper on your table.

Many phenomena encountered in our daily lives can be simply explained on the basis of refraction and reflection. Chapter 10 light reflection and refraction are one of the important chapters in class 10 science and the expected marks weightage of the chapter according to the latest marking scheme is 7 marks. Refraction of light part i. Light light reflection and refraction.

Place a mirror on the paper. Reflection and refraction of light you will need to run a simulation to do the lab. General physics lab phys 103a section 002 lab k1.
