Question1
Suppose you clarify two thin slits by monochromatic coherent light in air and find out that they create their first interference minima at ±30.00o on either side of the cbf. You then immerse these slits in a transparent liquid and elucidate them with the same light. Now you find that the first minima occur at ±20.00o instead. What is an index of refraction of this liquid?
Question2
Two speakers, 4.00 m apart, are driven by similar audio oscillator so that each one produces a sound with a frequency of 1360 Hz. The speed of sound in the room is 340 m/s. Find out all the angles relative to the usual center line in front of (and far from) speakers at that both frequencies interfere
(a) Constructively.
(b) Destructively.
what is the magnetic force per meter exerted by one bolt. After the first spring compresses a distance of 28.5 cm, the second spring acts with the first to increase the force as additional compression occurs as shown in the graph. The car comes to ..
A cat rides a merry-go-round while turning with uniform circular motion. At time t1 = 2.00 s, the cat's velocity is v1 = (3.50) + (4.00 m/s), find the magnitude of the cat's centripetal acceleration
