Araman line is observed at 4768.5 à, when acetylene was irradiated by 4358.3 a radiation, calculate the equilibrium vibrational frequency that causes the shift.

The equilibrium vibrational frequency that causes the shift is

Explanation:

Given that,

Wavelength of Raman line

Wavelength

We need to calculate the frequency

Using formula of frequency

For 4748.5 A

The frequency is

For 4358.3 A

The frequency is

We need to calculate the shift

Hence, The equilibrium vibrational frequency that causes the shift is

568.98

explanation:

its math

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
