Task 1: wave characteristics

A standing transverse wave is formed in a string that is 5.0m long. Both ends of the string are fixed. Eight loops are present in the standing wave. Answer the following questions about the wave. Make sure to show all work clearly.

1. Draw the standing wave. Label one node and one antinode.

2. Find the wavelength of the wave. fully explain how you found the wavelength.

3. if it takes a wave 6.0s to travel the length of the string, find the speed of the wave.

4. find the frequency of the wave.

task 2: speed of sound

Asaad, a grade 11 student, completed a lab activity to find the speed of sound in air using a closed-air column. he measured the temperature of the room to be 21 Celsius degree . using a tuning fork with a frequency of 1040Hz, he obtained the following resonant length for the closed air column.

L1 = 7.4cm

L2=22.5cm

L3=36.7cm

Questions:

a) use the resonant lengths to do three calculations to find the wavelength. find the average wavelength and use that in further calculations.

b) using the wave equation, what is the speed of sound in the air column?

c)what is the theoretical speed of sound in the room according to the temperature?
