spot the errors and point them out to me with the correction!!! thanks.......(not grammar, knowledge)
all waves require a medium to travel in. waves carry the medium from place to place. the height of the crest of the wave or the depth of the trough is called the amplitude. the distance between two crests is the wavelength. the number of waves per second is the frequency.

Not all waves require a medium to travel in. For example electomagnetic waves(light is an em wave) does not.
Waves travel through a medium , they do not carry the medium. Waves in a medium are just deformations of the medium which propagate in time.
The distance from the top of the wave to the trough is twice the amplitude. The distance from the crest to the trough is called the peak-to-peak value. The "distance" in units of time from crest to crest IS the PERIOD. The number of a complete wave cycles per unit time(second) is the frequency. :-)

1. not all waves require medium to propagate. Electromagnetic waves propagate supposedly without medium.
2. Waves do not carry medium. The waves in the medium are formed by disturbing medium particles and the disturbance propagates from particle to particle in the direction of wave propagation.
The rest looks pretty good!
