doppler effect
Refraction occurs when a wave crosses a boundary from one medium to another. A wave entering a medium at an angle will change direction.Diffraction refers to the "bending of waves around an edge" of an object. Diffraction depends on the size of the object relative to the wavelength of the wave.bestfahadali@yahoo.com
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

* Refraction occurs when a wave crosses a boundary from one medium to another. A wave entering a medium at an angle will change direction. * Diffraction refers to the "bending of waves around an edge" of an object. Diffraction depends on the size of the object relative to the wavelength of the wave. * Reflection:Waves can and do meet boundaries in their medium. When a wave meets a boundary, it can be reflected or transmitted. Reflection can be partial or complete. Reflection can also involve a phase flip (change of phase of 180 degrees.) * All these phenomena apply to electromagnetic waves, such as light waves, as well as to pressure waves and water waves.
Absorbance refers to the extent to which a sample absorbs light depends strongly upon the wavelength of light while wavelength refers to the Forms of electromagnetic radiation like radio waves, light waves or infrared (heat) waves make characteristic patterns as they travel through space

Inertia refers to the resistance of an object when there is a change in the motion of the object. The more inertia the object has, the more mass it will have.
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
phase change refers to the changes in the amplitude, and wavelength of the light when it passes from one medium to the other...
The word "wavelength" refers to the frequency of a wave. Wavelength is measured in hertz; the number of vibrations per second.

The final keyword indicates that a variable (identifier) can not change his value. In case the variable refers to a reference variable (an object) the values of variables inside (the object) can change but the reference can be reassigned (to another object).

physical weathering refers to weathering that occurs because of brute force, while chemical weathering refers to weathering that take place because change in the molecular composition of the substance
