Which statement(s) about alectromagnetic radiation are/is true
All types are invisisble as they travel through empty space
All types travel at the same speed
All types can travel through empty space
All of the above
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.
its fairly easy and safe to study
All of the above
A ray diagram is
a diagram that involves light rays
pictures a ray as a straight line with an arrow on one end
can be used to predict location, sizem and shape of shadows
all of the above
Which of the following is a way to measure wevelength?
the distance from trough to centre line
the distance from crest to crest
distance from top of the crest to the bottom of the trough
the distance covered by one wave in one second
Wave X has a longer wavelength thanwave Y
You cannot tell by looking at the diagrams
This statement is supported by the diagram
This statement is NOT supported by the diagram
Which statement is correct?
Both X and Y have the same wavelength
Neither amplitude nor wavelength is the same for X and Y
Both X and Y have the same amplitude
Both X and Y have the same frquencey and wavelength

violet
red
green
yellow
