Physics Light and Reflection Test Review

Light and Reflection test Review  Chap 13

1.  Know that all electromagnetic waves travel  at 3.0 X 10 (8) m/s   and solve for frequency given wavelength.


2.  Know that all electromagnetic waves travel  at 3.0 X 10 (8) m/s   and solve for wavelength given  frequency.

3.  Classify what part of the electromagnetic spectrum is used in actions like:  cell phone use,  microscope use,  microwave cooking,  television reception,  heat lamps,  tanning salons, etc

4.  Conceptual questions comparing speed, wavelength and frequency   in electromagnetic waves   for two waves  given some piece of data to compare them.  Ex1     radio vs  visible.  You must know the order in the electromagnetic spectrum.  Ex 2 red vs blue light

5.  Know all EM waves travel  have a single max speed = c  in a vacuum

6.  Know the mathematical relationship between frequency, wavelength and velocity

7.  Know the intensity distance relationship for light.  Ex Doubling distance affects the brightness of the light in what way?

8.  For flat mirrors know how angle of incidence and angle of reflection are measured  ( from the normal not from the mirrored surface)

9.  Describe flat mirror surface images in three words  ( also for concave and convex----Several questions)

10.  Be able to solve for f in a spherical mirror given radius of curvature or diameter

11.  Use mirror equation to solve for image or object distance or focal length given two of the three variables.

12.  Understand that f and q are negative for convex mirrors and  q is negative for a concave mirror when the object is between the f and the mirror.

13.  draw concave and convex images using ray diagrams

14.  Know the terms "additive"  =   light where primary colors are RGB   and "subtractive"  for pigment where primary colors are hello, cyan, magenta

15.  Explain what color is seen for adding either light or pigment or both.  Ex  Green tomato in red  light  or hello banana in red light.
