Two point sources produce waves of the same wavelength that are in phase. at a point midway between the sources, you would expect to observea)constructive or destructive interference depending on the wavelength. b)destructive interferencec)no interferenced)constructive interferencee)alternating constructive and destructive interference interference

d)constructive interference

Explanation:

For any two waves being equal in wavelength and in phase with each other will always lead to a constructive interference when there is a superposition of those two waves. Two waves being in phase means that each corresponding highs and low are aligned with each other. Their corresponding peaks occur at the same instant and at the same position. The two waves that are in phase can have a phase difference of one cycle i.e. 2π because after every cycle a wave repeats itself.

The sample with the lowest specific heat capacity will have the greatest temperature increase. in this case, it would be platinum.
