Awave with a frequency of 500 hz is traveling at a speed of 200 m/s. what is the wavelength ?

The wavelength of the wave is 0.40 m.

Frequency  f of a wave is defined as the number of waves traveling through a point in one second. Wavelength λ is the distance traveled by the wave in one complete time period. The speed of the wave v is related to frequency and wavelength by the expression,

Therefore,

Substitute 200 m/s for v and 500 Hz for f.

Thus, the wavelength of the wave is 0.40 m

The velocity of a wave is the product of the wavelength and the frequency of the wave. It is given by:

Velocity = Frequency * wavelength

Given that frequency = 500 Hz, velocity = 200 m/s, hence:

Velocity = Frequency * wavelength

200 = 500 * wavelength

Wavelength = 0.4 m

The wavelength of the wave is 0.4 m

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
