Two slits separated by a distance of d = 0.12 mm are located at a distance of D = 0.63 m from a screen. The screen is oriented p

arallel to the plane of the slits. The slits are illuminated by a coherent light source with a wavelength of λ = 540 nm. A wave from each slit propagates to the screen. The interference pattern shows a peak at the center of the screen (m=0) and then alternating minima and maxima. What is the pathlength difference between the waves at the second maximum (m=2) on the screen?

Answer:

The path-length difference is dsin\theta=1.08*10^{-3}mm

The angle is  \theta = 0.5157^o

Explanation:

  From the question we are told that

             The distance of separation is  d = 0.12 mm = 0.12*10^{-3} m

             The distance from the screen is  D = 0.63 m

              The wavelength is \lambda = 540nm = 540 *10^{-9}m

From the question we can deduce that the the two  maxima's are at the m=0 and m=2

   Now the path difference for this second maxima is mathematically represented as

                   d sin \theta = m \lambda

  Where ddsin\theta is the path length difference

Substituting values

        dsin \theta = 2 * 540*10^{-9}

                 dsin\theta = 1.08*10^{-6}m

converting to mm

               dsin\theta = 1.08*10^{-6} * 1000 mm

                        dsin\theta=1.08*10^{-3}mm

To obtain the angle we make \theta the subject

             \theta = sin ^{-1} [\frac{m \lambda}{d} ]

 Substituting values

             \theta = sin ^{-1} [\frac{1.08*10^{-6}}{0.12*10^-3} ]

               \theta = 0.5157^o

A volleyball player bumps a ball across a net with the velocity and angle shown below. What is the maximum height of the ball?
Marrrta [24]

Answer:

D. 12.4 m

Explanation:

Given that,

The initial velocity of the ball, u = 18 m/s

The angle at which the ball is projected, θ = 60°

The maximum height of the ball is given by the formula

                             h = u² sin²θ/2g  m

Where,

                           g - acceleration due to gravity. (9.8 m/s)

Substituting the values in the above equation

                            h = 18² · sin²60 / 2 x 9.8

                               = 18² x 0.75 / 2 x 9.8

                               = 12.4 m

Hence, the maximum height of the ball attained, h = 12.4 m

If you put a object in front of the mirror why does it appear the opposite way
UNO [17]
It is because that is how mirrors work, they reflect light, and since we see objects because we are seeing the light these objects reflect, what is reflected back by the mirror is what we see.
