Waves Speed

Wave properties continued The frequency and period of a wave are related. The frequency is the inverse of the period. frequency = 1 , or ƒ = 1/T period

Wave speed How can you calculate the speed of a wave? The speed of a wave is equal to wavelength divided by period, or to frequency multiplied by wavelength

Wave speed Wave speed equals wavelength divided by period. Speed = distance/time Wave speed = wavelength / period, or v = λ / T Wave speed equals frequency times wavelength frequency = 1 T Wave speed = frequency x wavelength, or v = ƒ x λ

Math Skills Wave speed The string of a piano that produces the not middle C vibrates with a frequency of 262 Hz. If the sound waves produced by this string have a wavelength in air of 1.30 m, what is the speed of the sound waves? List the given and unknown values Frequency = 262 Hz Speed = ? Wavelength = 1.30 m

Write the equation for wave speed v = ƒ x λ Insert the known values into the equation, and solve v = 262 Hz x 1.30 m v = 340.6 m/s

Wave speed The speed of the wave depends on the medium In general, wave speed is greatest in solids and least in gases In a given medium, the speed of waves is constant Kinetic theory explains differences in wave speed Light has a finite speed
