Snell's Law: Frequency, Velocity, Wavelength Ratios

[homevolend]

Homework Statement

A wave in a ripple tank moved from deep to shallow water with angle of incidence of 70' and angle of refraction of 55'. What are ratios in two media of the frequencies, velocities, wavelengths.

What does it mean by the ratio?

Homework Equations

sinθ1/sinθ2=v1/v2.

The Attempt at a Solution

I have no clue how to do this or understand the question. Would they be the formula sinθ1/sinθ2=v1/v2.

Need some urgent help thanks!

A ratio is like division, the ratio of a to be is written as a:b or a/b.

so if your ratio of a:b is 1:2 you can write a/b = 1/2 = 0.5.

For you relevant equation, you will also need to extend that to include wavelength.
