For stretching, think of the H2 molecule as
H---H. Now take your left hand on the left H and your right hand on the right H and stretch it like a rubber band.
For bending, look at the H2O molecule.
O--H
|
H
There is a stretching frequency for the OH bands. But the H atoms rock closer to each other and farther from each other also. That is the bending frequency.
What is a stretch (symmetric versus asymmetric)?
What is a bend?
