Diffraction:
Diffraction<span> describes how waves bend, or change direction, as they travel around the edges of obstacles. </span>Diffraction<span> occurs in water waves, </span>sound <span>waves, and light waves, but the amount of </span>diffraction <span>depends on the size of the obstacle or opening in relation to the wavelength of the wave.</span>
Answer:
Explanation:
Thomas is incorrect because acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
Answer: 94.07%
Explanation:
Percentage yield can be calculated by the formula
%yield = Experimental yield/Theoretical yield x100
Experimental yield = 7.93g
Theoretical yield = 8.43
%yield = Experimental yield/Theoretical yield x100
%yield = 7.93/8.43 x 100 = 94.07%
The dictionary definiton of light is:
the natural agent that stimulates sight and makes things visible.
I'll paraphrase/give a scientific definition:
Light is made of subatomic particles called photons, which jumps electron shells when they're excited, effecting the electromagnetic spectrum, creating visible light.
Hope this helps. Might not as I'm not perfect on this topic yet.
We have that the work function of the metal
