Question
238, The of describes the direction of the reflected beam given the direction of the incident beam, Based 1-1 and 1-2, state the law of reflection in words. Question 1-4: Compare the reflected intensity with the incident intensity. where did the rest of the light go? Question 1-5: What about the transmitted light? In what direction does it travel in the liquid in the transparent chamber? Prediction 12: Light from a Laseris incident as shown on the flat surface of a trans- parent material sketch the direction of the ray transmitted through the first deft) surface, and in words compare it to the incident ray in terms of the following Normal to the surface To test your predictions, you will need the following in addition to the mate- rials for Activity 1-i computer-based laboratory or graphical analysis software Real Time Physics Light and optics experiment configuration files. Activity 1-2: Snell's Law of Refraction 1. set up the chamber, laser, and glass rod on a piece of paper as in Activity 1-1. The laser beam should hit near the center of the flat surface. 2. Use the pencil to outline the chamber on the paper. 3. Mark two points on the paper along the incident beam using the pencil and label them with an A. Mark the point where the laser beam hits the surface. REALTIME PHYSICS: LIGHT AND OPTICS
Explanation / Answer
A. If a transparent chamber is kept in the path of the light, it will be having the refractive index different form that in the air, hence the light would bend inwards or outwards depending on if the refractive index of the chamber is denser or rarer respectively. Hence we can study refraction using the transparent chamber.
Answer 1-3
Law of reflection states that the incident ray, reflected ray and the normal lie in the same plane.
Answer 1-4
The reflected intensity will be less than the incident intensity. The rest of the intensity is transmitted ot absorbed.
Answer 1-5
The transmitted light would bend towards the normal, in the transparent liquid, as the density of liquid is greater than the density of air.
