Answer: In double slit case, you need to understand superposition on waves emerging from dirrerent slit.
Explanation: When passing a single slit, wave spread in all directions.
In double slit waves with equal wavelength travel different path and distance
trey travel is different . Waves meet each other in different positions in different phases. If phase are same, waves have contructive interference, crests of waves meet in same point. Amplitudes of waves are added together. If waves are in opposite phases, sum of amplitudes
ame subtacted and this is destructive interference. Sum of amplitudes are zero.
The answer is c capacitance
the reason why sound travels faster in solid is because the molecules in solid is more close to each other and they allow the waves of the sound to travel quickly or easily. and same reason why the sound travels fast in liquid that gas, it's because the molecules in liquid is closer to each other than the molecules in gas but they're not as close as solid hence why solid is the fastest at traveling sound
The sum of more than one velocity vector.
Or the sum of an initial velocity vector and an acceleration vector integrated over time.
C. a longer wavelength
Red has the longest wavelength and the wavelength decreases down the visible light spectrum to Violet which has the shortest wavelength
