What is a big difference between mechanical and electromagnetic waves?

• Mechanical do not need a medium and electromagnetic do.
• Mechanical waves are faster than electromagnetic.
• All mechanical waves are transverse.
• Electromagnetic do not need a medium and mechanical do.

This is how many waves pass a point in a given time. When this number is higher, this means that the waves carries more energy.

• amplitude
• wavelength
• speed
• frequency

This is the height between the crest and the rest line of a medium. The greater this is the greater the energy carried.

• wavelength
• frequency
• amplitude
• speed

This is the distance from one point on a wave to the same point on the next wave.

• speed
• amplitude
• wavelength
• frequency

Why is this lime green?

• Green reflects and the other colors are absorbed
• Green is absorbed and the others are reflected
• Green transmitted while others are reflected
• Blue and yellow light mix on the surface
