A)
Light waves travel very fast and sound waves travel much slower.
B)
Sound waves transmit energy while light does not transmit energy.
C)
Sound is a mechanical wave and needs a medium to travel through while light is an electromagnetic wave.
D)
Light is a mechanical wave and needs a medium to travel through while sound is an electromagnetic wave
B. constructive interference
C. destructive interference
D. destructive diffraction
Two or more waves combining to produce a wave with a smaller displacement is called destructive interference .
Destructive interference happens when the maxima of two waves are 180° out of phase a positive displacement of one wave is canceled exactly by a negative displacement of the other wave.
The formula for brighter patches resulting from constructive interference and darker patches resulting from destructive interference in a diffraction grating is:
Two or more waves combining to produce a wave with a smaller displacement is called destructive interference .
Hence, option C is correct.

destructive interference occurs when two or more waves combine to make a wave with a smaller amplitude C is your answer my friend :)
The kind of weather would an occluded front likely bring is much precipitation. The correct option is (b).
An occluded front happens when a warm front is passed by a cold front, which causes the cold air mass to elevate the warm air mass off the ground. Cloud formation and precipitation may result from this lifting of warm air.
When heated air is hoisted into the atmosphere and cooled, it condenses to form clouds. Ultimately results in rain or different types of precipitation.
Therefore, an occluded front is feasible to produce a good amount of precipitation. Depending on the atmospheric instability, cloudy skies, rain or showers, and occasionally thunderstorms can be found along an occluded front.
Hence, the kind of weather would an occluded front likely bring is much precipitation. The correct option is (b).
