According to the principle of superposition, when two waves meet, they reflect when two waves meet, they interfere when a wave meets a boundary, the angle of the reflected wave is equal to the angle of the incident wave when a wave meets a boundary, the angle of the refracted wave will be equal to the angle of the incident wave

The principle of superposition simply says that when two waves

cross the same place, the effect at that place is the sum of the

effects of each individual wave.

We know that when two waves meet, the amplitude of what happens

at their meeting place can be anything from zero to bigger than either

wave alone. THAT's superposition in action.

When two waves meet, they interfere.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
