Sample Question
Describe the nature of standing (stationary waves).

Standing waves are created by the collision of two waves with different speeds and amplitudes.

Standing waves are formed when a wave passes through a medium without any reflection or interference.

Standing waves have varying wavelengths and directions of propagation.

A standing wave is the product of the propagation of 1 wave against a wall and its reflected wave with the same speed, same wavelength, same amplitude, opposite direction. Because the wave is reflected, the energy that is propagated returns to the same point of origin. Velocity=displacement / time, and since there is no displacement, the wave has no velocity. As well, we say that no energy is propagated

Sample Question
Describe the photoelectric effect.

The photoelectric effect occurs at any frequency of light, but the intensity determines the number of electrons emitted.

The phenomenon where electrons are emitted from the surface of a metal after being exposed to light of a particular frequency called the threshold frequency. Light below the threshold frequency will not cause electrons to be emitted. Above the threshold frequency, the maximum KE of the electrons depends on the frequency of the incident light. The number of electrons emitted depends on the intensity of light, and not the frequency. Emission of electrons is instantaneous, and considers that light can act as particles called photons.

The photoelectric effect involves the emission of protons from a metal surface when exposed to light.

The photoelectric effect is a result of chemical reactions between light and the metal surface.
