Answer:
phase difference 
Explanation:
Phase difference is expressed as 
Where,
= phase difference
wavelength = 460nm
path difference = 920 nm
therefore
phase difference
2,450 miles. you have to do 700•3.5= 2,450
Answer:
The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
Explanation:
have a beautiful day ahead
Answer:
B
Explanation:
When something is moving at a constant velocity it's called the centripetal force. And the centripetal force accelerates radially outwards. It's like an ambulance siren. the sound waves are being exerted out into the atmosphere radiallly.
Answer:
similar wave amplitudes
Explanation:
When two waves travelling in the same medium have similar wave amplitudes they are less likely to interfere with each other destructively or constructively because the interference between waves occur when the amplitudes of the waves arrive a position in the medium in opposite directions hence they add up( superposition) or cancel each other out.
Hence if the waves have similar wave amplitudes the interference between the waves will be limited.
