Objectives for the Learner (Essentials of Inquiry) Conceptual Theme: To develop basic understanding of interrelationship between the angle of light rays and the area over which the light rays are distributed and the potential to affect changes in the temperature of materials.
Introduction to Light and Color
www.nasa.govEvery object we see has many rays of light coming from it either by reflection or because it is a light source such as a light bulb, the Sun, a star, etc. Each point on that object is a source of light rays. In the illustration below, the tip of the arrow is used as an example of a point on the object from which rays of light would be coming.

From your observations - conclude a rule about the direction light rays will bend when moving from materials of a higher optical density to one of a lower optical density. (example: plastic to air): 6. As light moves through a material with a high density – describe how does its speed of that light compare to the speed of light in a vacuum. 7.

Early History of X Rays - SLAC
www.slac.stanford.eduThe rays cast shadows, and were deflected by magnetic fields, but appeared to be immune to the ef-fects of static electric forces. As was to be characteristic of the new ray physics to come—the phys-ics of cathode rays, X rays, alpha rays, beta rays, gamma rays, and N rays— the nature of the cathode rays was in dispute, the British favoring ...
LIGHT - ncert.nic.in
ncert.nic.inA ray of light is an idealisation. In reality, we have a narrow beam of light which is made up of several rays. For simplicity, we use the term ray for a narrow beam of light. Draw lines showing the position of the plane mirror, the incident ray and the reflected ray on the paper with the help of your friends. Remove the mirror and the comb.
