Universal Wave

we started off class by talking about a universal wave. Universal wave equation- there is a relationship among speed,frequency and wave length that build true for all waves.

wavelength is the distance a wave travels in the time required for a complete oscillation (crest to crest). the time for one oscillation is called the period.

we know that :

an example would be:
the wavelength of a water wave is .80 m. if the frequency of the wave is 2.5 Hz(cycles per second). What is the velocity of the wave.
V= f λ

V=(2.5 Hz)(0.80)

v= .20 m/s

to end the class he assigned page 211 questions practice #1 and all section 6.3 questions for today in our physics 20 books
