Which best explains who is correct? Lexy is correct because angle R is between the incident wave, n = 0, and a diffracted wave. Lexy is correct because angle R includes the diffracted wave at n = 1. Jin is correct because angle S is measured from the barrier and includes n = 2, the wave that has the most diffraction. Jin is correct because angle S is between the dimmest order bands, n = 1 and n = 2.

A) Lexy is correct because angle R is between the incident wave, n = 0, and a diffracted wave

Explanation:

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
