A ray diagram is
pictures a ray as a straight line with an arrow on one end
can be used to predict location, sizem and shape of shadows

Why is the visible light model used to model electromagnetic radiation
it becoms visible when it interacts with matter
It has many properties in common with other types of E.M.R.
All of the above
its fairly easy and safe to study
Which statement about photons is true?
Each photon is shaped like a wave
Photons carry more energy as the Freq of EMR decreases
None of these are true
Photons carry more energy as the WL of the EMR decreases
