Marco is conducting an experiment. he knows the wave that he is working with has a wavelength of 32.4 cm. if he measures the frequency as 3 hertz, which statement about the wave is accurate?

a. the wave has traveled 32.4 cm in 3 seconds.
b. the wave has traveled 32.4 cm in 9 seconds.
c. the wave has traveled 97.2 cm in 3 seconds.
d. the wave has traveled 97.2 cm in 1 second.

Answer : (D) The wave has traveled 97.2 cm in 1 second

Explanation :

It is given that,

Wavelength of the wave is,

Frequency of the wave,

We know that the number of oscillation produced per second by a wave is called the frequency of the wave.

i.e.

Where,

T is the time period of the wave

Speed of the wave is given by :

So, the correct option is (D)" The wave has traveled 97.2 cm in 1 second ".

Hence, this is the required solution.

it has to be b, about 97 percent.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
