Example Questions
Example Question #41 : Waves
In seismology, the wave is a longitudinal wave. As an
wave travels through the Earth, the relative motion between the
wave and the particles is
Perpendicular
First perpendicular, then parallel
Parallel
First parallel, then perpendicular
Parallel
Longitudinal waves are waves whose particles travel parallel to the direction that the wave itself is traveling. Sound waves are another example of longitudinal waves.
Example Question #2 : Types Of Waves
Which of the following waves require a medium to travel?
Microwaves
Light Waves
Sound Waves
Sound Waves
Electromagnetic waves are the only type of wave that do not require a medium to travel. Light, radio and microwaves are examples of electromagnetic waves. Sound does require a medium to travel. In a vacuum sound waves cannot travel as there is no air to compress.
Example Question #42 : Waves
In a vacuum, the velocity of all electromagnetic waves
depends on the frequency
Is zero
Is nearly
depends on the amplitude
Is nearly
Electromagnetic waves all travel at the same speed which is the speed of light. The speed of light in a vacuum is nearly
Example Question #4 : Types Of Waves
A radio station broadcasts at a frequency of . If the broadcast is an electromagnetic wave, then what is its wavelength?
The relationship between wavelength and frequency is given by the equation , where
is the wavelength,
is the speed of light, and
is frequency.
We are given the values for frequency and the speed of light, allowing us to solve for the wavelength.
Example Question #43 : Waves
In seismology, the wave is a transverse wave. As an
wave travels through the Earth, the relative motion between the
wave and the particles is
First parallel, then perpendicular
Perpendicular
Parallel
First perpendicular, then parallel
Perpendicular
Transverse waves are waves whose particles travel perpendicular to the direction that the wave itself is traveling. Electromagnetic waves are another example of transverse waves.
