I'm going to quote something that might help you...
"The Doppler effect is the apparent change in the frequency of a wave motion when there is relative motion between the source of the waves and the observer. Well known examples include the change in pitch of an ambulance or police siren, as it approaches and then recedes from you, or the same effect from a passing train."
This is not mine I am simply quoting something that might help you.

Hi!
Okay, so -
In the scientific method, we're going to complete the following steps...
<em>ask a question
</em><em>perform research to gather information on said question
</em><em>develop a hypothesis (what you think will happen)
</em><em>experiment to determine if your hypothesis is true or false
</em><em>evalute data
</em><em>draw a conclusion</em>
<em>report results
</em>
<em />Hopefully, this helps you! =)
