Question

Although it may seem like it, a wave’s frequency and its speed are not the same. Picture yourself standing on the side of a road. A line of semitrucks is driving by you at 60 kilometers per hour. You time the semitrucks as they go by and notice that one truck passes you each second. Suddenly, the line of semitrucks ends and a line of small cars drives by you also going 60 kilometers per hour. You time the cars and notice that two cars pass you every second. Even though the speed of the trucks and cars is the same (60 kilometers per hour), more cars are passing you per second than trucks. Why? The answer is because the cars are shorter than the trucks; therefore, more of them can pass you by in the same amount of time.
a. What does the number of vehicles (cars or trucks) passing you each second represent?

b. What part of the wave would the length of the vehicles represent?

c. If two waves travel at the same speed but one has a shorter wavelength, what must happen to its frequency?

Answer 1

Answer:

A) the space inbetween the waves

B) frequency

C) the frequency gets higher
