- Q1What is light?Light is a form of energy30s
- Q2What is reflection of light?When light falls on a shiny surface, most of it bounces back.30s
- Q3What is incident ray?The ray of light falling on a reflecting surface is called incident ray30s
- Q4What is reflected ray?The ray of light coming back from a reflecting surface is called reflected ray.30s
- Q5What is normal?The perpendicular on reflecting surface at the point of incidence is called normal.30s
- Q6What is angle of incidence?The angle between incident ray and normal is called angle of incidence30s
- Q7What is angle of reflection?The angle between reflected ray and normal is called angle of reflection.30s
- Q8We can see objects because ofreflectiondiffractiontransmissionrefraction30s
- Q9When you see a straw in a glass of water it looks bent, why is thispolarizationreflectionrefractiondiffraction30s
- Q10Light travels through all transparent media at the same speedFalseTrue30s
- Q11What is refraction? Include a real world example as part of your explanationRefraction is the bending of light at the interface of two materials with different refractive indices is called refraction. Possible example: A straw in a glass of iced tea looks like it is bent because of the difference in densities and refractive indices of air and the liquid.30s
- Q12The imaginary line perpendicular to the boundary of two materials or to a reflective surface is called thephase linereflection pathnormalrefractive path30s
- Q13When a light ray traveling along the normal hits the boundary of two materials, it changes itsdirectionspeed30s
- Q14When a ray of light passes from air, a less dense medium, to glass, a more dense medium, the ray of light will bendaway from normaltowards the normal30s
