I want you to help me solve this question under physics.

Ripple tank waves of length 3cm travel at 15cms.
As they pass into shallow water covering a glass sheet they slow down to 10cms.
a) Find the original frequency of the waves.
b) Calculate their new wavelength.

a) c=f*lambda, and wavelength is 3cm.
b) frequency doesnt change as it enters into a new medium.
so use the frequency calculated in part a.
and use the equation again with new value for c.
