<u><em>Answer:</em></u>
Destructive interference
<u><em>Explanation:</em></u>
<u>Interference</u> is a term used to refer to the combination of two waves or their overlap
<u>There are two types of interference:</u>
<u>1- Constructive interference:</u> This happens when the waves overlap/combine to produce a resultant wave with a larger displacement
<u>2- Destructive interference:</u> This happens when the waves overlap/combine to produce a resultant wave with a smaller displacement
Hope this helps :)
Answer:
1) d 2) a 3)
Explanation:
4) B would be brighter and more useful than A because A is all bunched up together without any room for extra energy meanwhile B has plenty of room for more energy
Answer:
b. more rapidly in the vertical direction
Explanation:
Atmospheric Pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation.
Pressure decreases with increasing altitude because at higher altitudes both the height of overlying air column and its density decreases. Hence the answer.
A real image is smaller than the object
