Solve each of the following equations. Please format your answer as a decimal where applicable. Velocity and speed may be interchanged sometimes.

Wavelength Equation: Speed $$ Frequency

a$.$ What is the wavelength of a wave that has a velocity of $5\frac{m}{s}$ and a frequency of $5Hz?$

Wavelength $=$ meter

b$.$ A wave that has a velocity of $7m\frac{m}{u}s$ and a frequency of $3\mathrm{.}5MHz$ has a wavelength of:

Wavelength $=mm$

c$.$ What is the frequency of a wave that propagates at a speed of $1\mathrm{.}5m\frac{m}{u}s$ with a wavelength of $3mm?$

Frequency $=MHz$
