A wave traveling in water has a frequency of 250 Hz and a wavelength of 6.0 N. What is the speed of the wave?
enyata [817]
The speed of a wave is determined by the product of the frequency and the wavelength; we already have the wavelength and the frequency, so all we need to do is multiply them by each other and use our proper unit of measure.

Velocity (speed) = Frequency x Wavelength
V = 250 x 6
V = 1500

Your answer is 1500 m/s.

I hope this helps!

Brilliant_brown [7]

d. both a and b

Explanation:

Seismic waves are both transverse and compressional or longitudinal waves.

A seismic wave is an elastic wave that causes a sudden disturbance in earth materials.

  • Seismic waves are both longitudinal and transverse waves.
  • There are two main types of seismic waves which are the surface and body waves.
  • The surface waves runs on the earth surface. These are the rayleigh and love waves.
  • The surface waves causes damages on the earth surface as they are both longitudinal and transverse.
  • Body waves moves within the earth surface. They are p-waves and s-waves.
  • P-waves are longitudinal or compressional waves that propagates within the earth surface.
  • S-waves are transverse waves that moves perpendicularly to their direction of propagation.
