LIGHT AND LASERS
ID the following terms:
Electromagnetic spectrum
laser
refraction
reflection
Magnification
photon
infrared light
ultraviolet light
Wavelength
frequency
convex lens
concave lens
Corresponding angles
transversal
alternate exterior angles
Rank the following types of EM waves from lowest to highest energy:
Radio waves – gamma rays – x rays – visible light – microwaves – infrared waves
If the intensity of light is 6400 lumens one foot from the source, what is it’s intensity
two feet from the source?
What happens to an electron of an atom when that atom releases a photon?
What is the relationship between the angle of incidence and the angle of reflection?
If the angle of incidence of a light to a mirror is 40 degrees, what is the angle of
reflection?
What are some common uses for lasers?
How does an object’s color affect how it absorbs and reflects certain wavelengths of
light?
Which color(s) of light would be reflected by blue wall? Which color(s) of light
would be absorbed the most by a blue wall?
What is the speed of light? Be able to convert the speed of light into several
different dimensional units.
How many frequencies of light are in each laser beam? How many energy levels of
light are in each laser beam?
What happens to light when it passes through a concave lens? convex lens?
Know the magnification (< or > 1) for convex and concave lenses
How is a lens’s magnification calculated?
