Using a 679 nm wavelength laser, you form the diffraction pattern of a 1.1 mm wide slit on a screen. You measure on the screen t
sveta [45]

To solve the problem, apply the concepts related to constructive and destructive interference. For this purpose, we will start by defining the distance from the dark fringe from the central maximum in terms of the slit separation, the number of fringe the wavelength and the distance of the screen to the slit. Mathematically this is,

y_n = \frac{(2n-1)\lambda D}{2d}

D = \frac{2dy_n}{(2n-1)\lambda}

Here,

d = Slit separation

n = Number of fringe

y_n = Distance of the dark fringe from the central maximum

D = Distance of the screen to the slit

\lambda = Wavelength

Our values are given as,

\lambda = 679nm = 679*10^{-9}m

d = 1.1mm = 1.1*10^{-3}m

y_{14} = 8.01cm = 8.01*10^{-2} m

n = 14

Replacing,

D = \frac{2(1.1*10^{-3})(8.01*10^{-2})}{(2(14)-1)(679*10^{-9})}

D = 9.61m

Therefore the screen is located from the slit to 9.61m

Answer:

10.21m/s²

Explanation:

Radial acceleration, also known as centripetal acceleration, refers to the acceleration of an object along the circular radius. It can be calculated using the formula:

a(r) = v²/r

Where a(r) = radial acceleration

v = velocity

r = radius of the circular path

According to the information provided in the question, velocity (v) = 17.5m/s, radius = 30m. Hence;

a(r) = v²/r

a(r) = 17.5²/30

a(r) = 10.208333

a(r) = 10.21m/s²

What wave is caused by vibration <br><br> sound waves, water waves, or seismic waves.
icang [17]

Answer:

In the first part of Lesson 1, it was mentioned that sound is a mechanical wave that is created by a vibrating object. The vibrations of the object set particles in the surrounding medium in vibrational motion, thus transporting energy through the medium.
