Is it true or false that the greater the frequency of the wave in a particular medium the greater the speed of the medium.?
False. The medium is assumed to be resting in any case. If you refer to the speed of the wave, in the case of most wave that is more or less independent of the wave's frequency.
What happens to the speed and wavelenght and frequency of a wave when it reaches the boundary between two media?
Frequency never changes since it depends only on source. Speed can either increase or decrease, depending on the direction of travel of light. This would cause an increase or decrease in wavelength respectively. Speed increases when light travels from an optically denser medium to an optically less dense one. (For example, when light travels from water to air) Speed decreases when light travels from an optically less dense medium to an optically denser medium.
Explain how amplitude and pitch affect changes in waves?
In case of mechanical waves, ie waves propagating through material medium the amplitude of the waves decides the intensity of the waves as intensity is directly proportional to the square of its amplitude. Pitch is related to the frequency of the wave. As pitch increases then in one second more number of waves would cross a particular point in the medium. If velocity of the wave in the medium remains constant, the wavelength gets reduced as the pitch increases.
What is the vibration at an objects natural frequency called?
medium
Why a medium is called as dispersive medium?
group velocity depends upon the frequency of the wave. such type of materials called dispersive medium.
What are the definitions of amplitude frequency and wavelenght?
Speed c of the wave in the medium = frequency ftimes wavelength lambda.

False. The medium is assumed to be resting in any case. If you refer to the speed of the wave, in the case of most wave that is more or less independent of the wave's frequency.
Relationship between wave speed and frequency?
For a particular type of wave, in a specified medium, the multiple of the two is a constant.
Why some waves travels fastest?
it depends on the kind of material medium it occurs on. and it's wavelenght.

If seven wavelengths pass in one second - what is the frequency?
7 hertz. Since frequency of the wave motion is defined as the number of waves ie number of wavelengths crossing a particular point in the medium in one second.
Why frequency of light is not change When it enter from a rarer medium to denser medium?
Frequency is a function of the energy level of the photon. Changing the medium does not change that energy level.
Sound waves whose frequency is 300 Hz have a speed relative to sound waves in the same medium whose frequency is 600 Hz that is?
Since velocity of wave = frequency x wavelength (or v=fλ), and velocity is assumed to be the same for both since they're in the same medium,f1λ1 = f2λ2300λ1 = 9000λ2λ1/λ2 = 9000/300 = 30Thus, the wavelength of the 300Hz frequency sound wave is 30 times greater than the 9000Hz frequency sound wave.

What increases when sound wave travel in solid from gas medium frequency or wavelength?
Velocity increases when sound waves travel from gas medium to solid medium. As velocity = frequency * wave length and the frequency does not change, v is directly proportional to the wave length... Hence the wavelength increases.
What is the relationship between the frequency and wave medium?
There's no relationship between the frequency and the medium. The frequency of a wave is determined by the source. Once the wave leaves the source and sets out on its journey, the frequency doesn't change, regardless of what kind of stuff the wave encounters and has to travel through.
