What is amplitude?
the max. distance that the particles of the medium moving away from their rest positions as a wave passes through
How can you increase the amplitude of a wave of a wave in a rope?
You can increase the amplitude of a wave in a rope by moving your hand up and down a greater distance.
What does the wavelength of a transverse wave measure the distance of?
the wavelength of a transverse wave measures the distance of the crests
The EM spectrum has this many types

What is wavelength?
the distance between two corresponding parts of a wave
What is "amplitude of transverse waves"?
the maximum distance the medium moves up or down from its rest position
How do you find the wavelength of a wave?
To find the wavelength of a wave, you have to have speed being divided by the frequency.

Energy
What does a wave do before it starts to repeat?
A wave travels a certain distance before it starts to repeat.
How can you increase the frequency using a slinky?
By moving your hand up and down more quickly, it increases the frequency.
