1.What is the speed of light 300,000,000 ms answer
2.What is the law of reflection? “The angle of incidence = the angle of reflection” answer
3. What is a “normal” line answer A dotted line drawn at right angles to a surface
4. What is meant by the term refraction answer Refraction is when light slows down as it passes from air into glass. This can cause it to change direction.
5. What happens if light passes from air into glass at an angle to the normal? It slows down and bends towards the normal. answer
6. What is meant by the term “critical angle” The angle above which light in glass is not refracted out but is totally internally reflected answer
7. What type of lens brings parallel rays of light to a a focus point? A convex or converging lens answer
8. What does a prism do to a ray of white light? Splits it into a visible spectrum. answer
9.What is the name of the family of waves that all travel at the speed of light? The Electromagnetic Spectrum answer
10.What is the order of the sections in the EM spectrum starting with the lowest frequency? Radio &TV, microwaves, Infrared, Visible, Ultra Violet, X-Rays, Gamma Rays answer
11. Name a detector used to detect Infrared radiation. Thermal imaging sensor or photodiode or skin. answer
12. Which section of the EM spectrum has the highest energy ? Gamma rays Gamma rays answer
13. Are light waves transverse or longitudinal? Transverse answer
14. What kind of light is used to send information through a fibre optic cable ? Laser light Laser light answer
15. What type of lens would correct the vision of a short sighted person A concave or diverging lens. answer
16. What is the wavelength of a radio wave that has a frequency of 102.5 MHz ? wavelength = v/f = 300,000,000 / 102,500,000 = 2.93m answer
A review for the quiz. Sound waves from a radio generally travel in which medium? a) air b) light c) earth d) water.
LIGHT. Reflection of light When light is reflected off of a mirror it forms an image. Mirror Incident ray Reflected ray Normal.
How do eye glasses work?. BUT first, let’s review! What is energy? The capacity for doing work (or to produce heat) Can energy be created? no or destroyed,
