The index of refraction of silicate flint glass for red light is 1.620 and for violet light is 1.660. A beam of white light in t

his glass strikes the glass–air interface at a 22.50° angle of incidence and refracts out into air. What is the angular separation between the red and violet components of the spectrum that emerges from the glass?4

Answer:

0.33 degree

Explanation:

refractive index for red light = 1.62

refractive index for violet light = 1.66

angle of incidence, i = 22.5 degree

Use Snell's law for the red light

refractive index for red light = Sin i / Sin r

Where r be the angle of refraction for red light

1.62 = Sin 22.5 / Sin r

Sin r = 0.2362

r = 13.66 degree

Use Snell's law for the violet light

refractive index for violet light = Sin i / Sin r'

Where r' be the angle of refraction for violet light

1.66 = Sin 22.5 / Sin r'

Sin r' = 0.23053

r' = 13.33 degree

Angular separation between red and violet components = r - r'

                                                                  = 13.66 - 13.33 = 0.33 degree

The angular speed of the rotor in a centrifuge increases from 420 to 1420 rad/s in a time of 5.00 s. (a) Obtain the angle throug
9966 [12]

Answer:

a) θ = 2500 radians

b) α = 200 rad/s²

Explanation:

Using equations of motion,

θ = (w - w₀)t/2

θ = angle turned through = ?

w = final angular velocity = 1420 rad/s

w₀ = initial angular velocity = 420

t = time taken = 5s

θ = (1420 - 420) × 5/2 = 2500 rads

Again,

w = w₀ + αt

α = angular accelaration = ?

1420 = 420 + 5α

α = 1000/5 = 200 rad/s²

A clay vase on a potter's wheel experiences an angular acceleration of 5.69 rad/s2 due to the application of a 16.0-n m net torq
Digiron [165]
The equivalent of the Newton's second law for rotational motions is:
\tau = I \alpha
where
\tau is the net torque acting on the object
I is its moment of inertia
\alpha is the angular acceleration of the object.

Re-arranging the formula, we get
I= \frac{\tau}{\alpha}
and since we know the net torque acting on the (vase+potter's wheel) system, \tau=16.0 Nm, and its angular acceleration, \alpha = 5.69 rad/s^2, we can calculate the moment of inertia of the system:
I= \frac{\tau}{\alpha}= \frac{16.0 Nm}{5.69 rad/s^2} =2.81 kg m^2
