Question

When a surfer rides an ocean wave on her surfboard, she is actually riding on

A.a crest that is toppling over
B.a trough of the wave
C.the rest position of the wave
D.a region of rarefaction


Have you ever watched a surfer or a suring movie? Actually, none of these choices are quite right. To stay with a wave, a surfer rides the "leading edge" betweeen a trough and the crest. If he or she is on the crest, it will pass them by. There really is no "rest position" - the water is moving everywhere. These are poor multiple choices, in my opinion.


I'm sorry, them are the choices I was given
