Which statement(s) about alectromagnetic radiation are/is true
All types travel at the same speed
All of the above
All types are invisisble as they travel through empty space
All types can travel through empty space
Why is the visible light model used to model electromagnetic radiation
All of the above
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
A ray diagram is
pictures a ray as a straight line with an arrow on one end
a diagram that involves light rays
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 crest to crest
the distance from trough to centre line
the distance covered by one wave in one second
distance from top of the crest to the bottom of the trough
Wave X has a longer wavelength thanwave Y

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 frquencey and wavelength
