What is the maximum number of lines per centimeter a diffraction grating can have and produce a complete first-order spectrum fo

Vitek1552 [10]

Answer:

1315789.47368 lines/m

Explanation:

m = Order = 1

$sin\theta$ = 1 For maximum condition

$\lambda$ = Wavelength = 760 nm maximum

From Rayleigh criteria we have the expression for the gap

$d=\dfrac{m\lambda}{sin\theta}\\\Rightarrow d=\dfrac{1\times 760}{1}\\\Rightarrow d=760\ nm$

The number of lines is the reciprocal of the slit distance

$n=\dfrac{1}{d}\\\Rightarrow n=\dfrac{1}{760\times 10^{-9}}\\\Rightarrow n=1315789.47368\ /m$

The number of lines is 1315789.47368 per meter

Answer:

v = 0.0251 km/h

Explanation:

Given that,

The average distance from its center of mass of 1000 meters.

The time taken is 24 hours and 57 minutes to complete one orbit

We need to find the orbital velocity of the spacecraft OSIRIS-REx.Let it is v. SO,

$v=\dfrac{2\pi r}{t}$

Putting all the values,

$v=\dfrac{2\pi \times 100}{24\ hours\ and\ 57\ minutes}\\\\v=\dfrac{2\pi \times 100}{(86400+3420)}\\\\v=0.00699\ m/s$

v = 0.0251 km/h

So, the average orbital velocity is 0.0251 km/h.

During wave motion, the motion of particles to one side of the rest position will be (unrelated to,the same as) the motion to th

pentagon [3]

The motion of particles to one side of the rest position will be the same as the motion of the other side of the rest position in a wave motion. because in a wave motion or wave function, it symmetrical. meaning the motion on the other side will be identical to the other side of the rest position
