For the following three parts, select an answer and briefly explain your reasoning for each! Is the frequency of the wave on string 1 the same or different than the frequency of the wave on string 2?

Question
Please I need help
You tie two different strings together and attach them
to a wall very far away (see picture; wall not shown).
The two strings are made of different materials and
have different thicknesses and masses.
The location of your hand is x = 0 m and the strings
are attached at x = 1.50 m.
x=0m
Connection between
Strings 1 and 2
iii.
String 1: Thick String
x = 1.50 m
Wall
String 2: Thin String
At time t = 0, you raise string 1 2.00 cm above equilibrium and then begin to shake it up and down in a
sinusoidal fashion, causing a continuous wave moving to the right, going directly from string 1 to string 2
(ignore the reflection of the wave upon hitting the wall).
For the following three parts, select an answer and briefly explain your reasoning for each!
Is the frequency of the wave on string 1 the same or different than the frequency of the wave on
string 2?
ii.
Is the wave speed of the wave on string 1 the same or different than the speed of the wave on
string 2?
Is the wavelength of the wave on string 1 the same or different than the wavelength of the wave
on string 2?

A friend, with a timer, watches you shake the strings and finds that your hand completes 18.0 cycles in 4.00
seconds. Another friend takes a photograph of the strings, which is shown below.
