High school physics, please show all work

The fundamental (1st harmonic) on the highest pitch violin string is 660 Hz and the string is 32 cm long.

A. What will the wavelengths for the first three harmonics be?

B. What will the frequency for the first three harmonics be?

C. What will the velocity for the first three harmonics be?

D. How will the velocity of the waves on the string compare to the velocity of the sound waves the string produces?

(remember the ratio of the harmonics makes a trumpet sound different from a violin.)

note: draw a diagram for parts A, B, C & D. please label everything + explain thoroughly
