PPT-Concave and Convex

MIRRORS Concave Mirrors A con cave mirror has a surface that curves inward like a cave or a bowl It follows the law of reflection however when parallel light rays approach a curved surface and strike at different points on the curve each ray will reflect at a slightly different direction .

The most common type of curved mirror is a spherical mirror. A spherical mirror has the shape of a section from the surface of a sphere. Curved Mirrors. Concave mirror – the inside surface of the mirror is polished. Origami World. David . Fouhey. , . Abhinav. Gupta, Martial Hebert. 1. 2. 3. Local Evidence. 4. Hoiem. et al. 2005, .

The smooth surface of the lake reflects light rays so that the observer sees an inverted image of the landscape.. Law of Reflection. The law of reflection states that the angle of reflection is equal to the angle of incidence. . Important vocabulary. Reflection- . the bouncing back of light from a surface..

Transparent substances refract light. It’s not magic… it’s science!. How light Refracts. Refraction is due to changes in the speed of light.. In space, light travels at 300 000 km/s. Space is a vacuum, and there are no particles to get in the way of light and slow it down.. S4P1 Students will investigate the nature of light using tools such as mirrors, lenses, and prisms. ..  . c. .
