V=Xf; speed = wavelength x frequency f= 1/T; frequency = 1/Period
Problems: 1. The frequency of a wave is 4.0 x 10 Hz. What is its wavelength?

2. A wave with a frequency of 31,200 Hz and travels at 790m/s? What is the wavelength in centimeters?

3. A wave has a wavelength of 25cm and a velocity of 630 m/s, what is the frequency?​

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.
