Indicate valleys, hills, steepness and gentleness of slopes.
Answer:
Since the wavelength would be reduced by the factor of N where N is the index of refraction, fringes would be be closer to one another.
(Similar to the difference of fringes of red light and blue light.)
Answer:
Transverse wave
Explanation:
In transverse waves, particles of the medium vibrate to and from in a direction perpendicular to the direction of energy transport. 4. A transverse wave is traveling through a medium.
Answer:
im pretty sure thats called friction, or did you mean something else?
Answer:
T = 8.19 s
, = 23 m / s
Explanation:
In the simple harmonic motion the equation that describes them is
y = A cos wt
Acceleration can be found by derivatives
a = d²y / dt²
v = dy / dt = - Aw sin wt
a= d²y / dt² = - A w² cos wt
For maximum acceleration cosWT = + -1
= -A w2
w = RA (/ A)
w = RA (1.8 9.8 / 30.0)
w = 0.767 rad / s
The angular velocity is related to the frequency
w = 2π f
f = 1 / T
w = 2π / T
T = 2π / w
T = 2π / 0.767
T = 8.19 s
For maximum speed the sin wt = + -1
= A w
= 30.0 0.767
= 23 m / s
