Nature of light pt2

DEPENDS ON HOW IT IS MEASURED

LIGHT STRIKING A METAL SURFACE

GOES FROM HIGH TO LOW ENERGY

A PARTICLE WHEN GIVING ENERGY

A WAVE WHEN MOVING

ENERGY OF PHOTON > BINDING ENERGY

WAVELENGTH DIFFERENT FOR EACH ELEMENT

LIGHT BEHAVING IN 2 WAYS

EXCESS ENERGY MAKES ELECTRONS EJECT

MINIMUM THRESHOLD OFF ENERGY

NEGATIVE = WENT FROM HIGH TO LOW ENERGY

VISIBLE SPECTRUM OF LIGHT

WAVELENGTHS ARE DISCRETE

CALCULATES DIFFERENCE IN ENERGY STATES

POSITIVE = WENT TO AN EXCITED STATE

INCREASE W/ WAVELENGTH DECREASING
