What is the difference between harmonics and ripple?

Ripple (as it usually applies to the DC output from a power supply) are usually artifacts from the rectification process.
Harmonics don't just apply to ripple: anytime you're drawing large amounts of power or have large non-linear loads attached to your mains power, you're deforming the sinusoidal waveform that's coming in. If you've studied Fourier series, you know that anything that isn't a perfect sinusoid will have higher frequency components. Since the ripple isn't perfectly sinusoidal, it'll have higher frequency components, often at a significant amplitude.
