In your research lab, a very thin, flat piece of glass with refractive index 1.20 and uniform thickness covers the opening of a

liraira [26]

Answer:

(a). The thickness of the glass is 868 nm.

(b). The wavelength is 3472 nm.

Explanation:

Given that,

Refractive index = 1.20

Wavelength = 496 nm

Next wavelength = 386 nm

We need to calculate the thickness of the glass

Using formula for constructive interference

$2nt=(m+\dfrac{1}{2})\lambda$

Put the value into the formula

In first case,

$2nt=(m+\dfrac{1}{2})496$ .....(I)

In second case,

$2nt=(m+1+\dfrac{1}{2})386$

$2nt=(m+\dfrac{3}{2})386$ .....(II)

From equation (I) and (II)

$(m+\dfrac{1}{2})496=(m+\dfrac{3}{2})386$

$110m=336$

$m=3.0$

Put the value of m in equation (I)

$2nt=(2+\dfrac{1}{2})496$

$t=\dfrac{(3+\dfrac{1}{2})496}{2\times1}$

$t=868\ nm$

The thickness of the glass is 868 nm.

(b). We need to calculate the wavelength

Using formula of constructive interference

$2nt=(m+\dfrac{1}{2})\lambda$

$\lambda=\dfrac{2nt}{(m+\dfrac{1}{2})}$

Put the value into the formula

$\lambda=\dfrac{2\times1\times868}{\dfrac{1}{2}}$

$\lambda=3472\ nm$

Hence, (a). The thickness of the glass is 868 nm.

(b). The wavelength is 3472 nm.

An object moves in a circular path at a constant speed. What is the relationship between the directions of the object's velocity

Reil [10]

Answer:

Explanation:

When an object is in circular motion, the direction of velocity is in the direction of tangent to the circle and acceleration is always directed towards the radial direction. This means that velocity is always perpendicular to acceleration of the object.

Hence option (b)-The velocity and acceleration vectors are perpendicular is correct.
