Question

The diagram shows the identification of two types of waves.



Which question, represented by X on the diagram, helps to identify the type of wave?

a
Does the wave have an amplitude?
b
Do the particles transfer energy?
c
Does the wave require a medium to travel?
d
Do the particles travel perpendicular to the wave?
Question 9 (1 point)
Which wave would have the lowest energy?



A



B



C


a
the all have the same energy
b
A
c
B
d
C

Answer 1

1) d — “Do the particles travel perpendicular to the wave?” (that distinguishes transverse vs longitudinal waves)

2) d (C) — energy depends on amplitude and frequency (shorter wavelength = higher frequency). Wave C has the lowest amplitude/lowest frequency, so it has the lowest energy.
