Answer:
A laser is created when the electrons in atoms in special glasses, crystals, or gases absorb energy from an electrical current or another laser and become “excited.” The excited electrons move from a lower-energy orbit to a higher-energy orbit around the atom's nucleus.
False they simple machines do not reduce the amount of work you do it would just reduce the amount of force you use.
Answer:
Diffraction and Interference of light support the wave theory of light.
Explanation:
Complete Question
Which phenomena support only the wave theory of light? Check all that apply.
1.reflection
2.refraction
3.diffraction
4.interference
5.photoelectric effect
Solution
There are two theories/schools of thoughts that light possesses wave and particle properties.
The wave properties of light explain that light is made as a result of interactions of electric and magnetic fields, hence, light is regarded as an electromagnetic wave that propagates without the need for a material medium and moves in a direction perpendicular to the direction of the oscillations or direction of the cause/source of the light waves.
Properties that support the wave properties of light are diffraction (ability to navigate or bend around obstacles) and Interference (two light waves can combine or superimpose to form a single resultant light wave with amplitude greater, lower or equal to the amplitudes of the two constituting light waves).
Hope this Helps!!!
Stencils, ruler, penciles thing like that.
