It takes 5.0 seconds for a wave with a wavelength of 2.5 m to travel past your location. what’s the period of the wave. what is the frequency of the wave and what’s the speed of the wave

(a) Period of the wave
The period of a wave is the time needed for a complete cycle of the wave to pass through a certain point.
So, if an entire cycle of the wave passes through the given location in 5.0 seconds, this means that the period is equal to 5.0 s: T=5.0 s.

(b) Frequency of the wave
The frequency of a wave is defined as

since in our problem the period is , the frequency is


(c) Speed of the wave
The speed of a wave is given by the following relationship between frequency f and wavelength :

Sublimation- which change of state is shown in model

Well it depends on the object or substance
