Front

Define wavelength in the context of light.

Back

Wavelength is the distance between successive peaks of a wave, determining the color of light.

Front

What is the relationship between wavelength and energy in light?

Back

Longer wavelengths correspond to lower energy, while shorter wavelengths correspond to higher energy.

Front

Explain the concept of polarization of light.

Back

Polarization is the orientation of light waves in a particular direction, affecting how light interacts with materials.
