Can be Doppler shifted, reflected, refracted,
MrMuchimi

Waves: can be Doppler shifted, reflected, refracted,  diffracted, and can undergo constructive and  destructive interference.

A wave refers to a disturbance in a medium that progressively transports energy from its source to another location, without transporting matter.

In Physics, there are two main (2) types of wave and these are;

  • <u>Mechanical waves:</u> an example is sound wave, which requires a medium for its propagation.
  • <u>Electromagnetic waves:</u> an example is light wave, which doesn't require a medium for its propagation and can travel through a vacuum or an empty space.

Basically, some of the phenomenon associated with waves include the following:

I. Doppler shift (Doppler effect).

II. Reflection.

III. Refraction.

IV. Diffraction.

V. Constructive interference.

VI. Destructive interference.

In conclusion, all waveform can be Doppler shifted, reflected, refracted,  diffracted, and can undergo constructive and  destructive interference.

Stellar-sized black holes form when a star explodes in a supernova. True or False
svetoff [14.1K]

Answer:

True

Explanation:

Stellar-sized black holes form when a star explodes in a supernova is a true statement. Supernova occurs when a huge size star collapses into itself. This explosion is massive such that parts of the stars are thrown apart. And this phenomenon gives rise to super massive black holes. Supernova occurs when the core becomes very heavy and star is not able to hold its won weight.
