Electromagnetic waves.

Probability waves.

Gravitational waves.

Mechanical waves.

Energy is doubled due to constructive interference.

Energy is periodically zero when destructive interference occurs.

The total energy is conserved and remains constant within the system.

Energy decreases over time due to wave cancellation.

Two opposite-phase light wavelength waves causing destructive interference leading to darkness.

Multiple sound waves combining at different frequencies producing beats heard by observers.

Two identical waves perfectly aligned crest-to-trough resulting in constructive interference.

Extremely high amplitude waves creating nonlinear effects within the medium.

Decreases due to energy dissipation.

It remains constant regardless of conditions.

Alternates between zero and maximum value periodically.

Increases explosively without limits.

Hertz

Newton

Joule

A larger continuous pulse that travels in the direction of the original pulses.

A larger single pulse is formed momentarily as the two pulses combine and then separate again.

Smaller diminished pulses emerge past the meeting point.

Permanent alteration of shapes and sizes, forming a new, persistent waveform.

Kinetic energy after collision is greater if one object moves faster than prior velocity.

Total kinetic energy before collision equals total kinetic energy after collision.

Kinetic energy before collision is less than after collision due to momentum transfer.

Kinetic energy cannot be determined unless masses of objects are known.

f = T/λ

f = $\frac{1}{T}$

f = λ/T

f = T^2
