Interference can arise with one source of waves where the waves travel different distances before meeting. The difference in the distance travelled (the path difference) must be a full number of ...

A broad source is equivalent to a large number of fine sources. Each pair of fine sources will give its own pattern. The fringes of different interference patterns will overlap. The two interference ...

These happen when multiple wave patterns align, called wave interference, magnifying wave heights. The timing of high tide adds another layer of risk, with residual effects from the recent king ...

This is the Crab Pulsar, and within its radio pulses is a strange signal that has puzzled astronomers for years. Called the ...
