PHY wave frequency wavelength

想問如果frequency上升,wavelength係咪會下降?
This is true for waves travelling in the same medium.

仲有distance下降,咁velocity係咪會上升?
Velocity of wave depends on the properties of the medium in which the wave travels. The distance travelled is not a factor affecting the wave velocity.

仲有點解高既amplitude會有高既K.E?
The kinetic energy (KE) of the wave is the energy conveyed by individual particles constituting the wave.
Since KE = (1/2)m.v^2
where m is the mass of individual particles
v is the vibrational speed of the particle
But maximum speed v(max) = A.w
where A is the amplitude of the wave
w is the angular frequency of the wave
hence, KE(max) = (1/2)m[v(max)]^2 = (1/2).m.w^2.A^2
i.e. KE(max) is proportional to A^2
