Answer:
Explanation:
For light passing through a single slit, the position of the nth-minimum from the central bright fringe in the diffraction pattern is given by
where
is the wavelength
D is the distance of the screen from the slit
d is the width of the slit
In this problem, we have
is the wavelength of the red light
D = 14 m is the distance of the screen from the doorway
d = 1.0 m is the width of the doorway
Substituting n=1 into the equation, we find the distance between the central bright fringe and the first-order dark fringe (the first minimum):
Answer:
B
Explanation:
Speed is the magnitude of the velocity vector, so it can never be negative.
Answer:
Option B. magnitude of displacement of a sound pressure wave
Explanation:
Amplitude is simply the maximum displacement of a wave from its mean position.
