Students in a science class observe a model that illustrates that when white light passes through a prism, each wavelength is bent at a slightly different angle due to the wavelength of the color of light. Students are asked to describe this phenomenon in terms of what it is called, which color of light gets bent the least and therefore has the lowest frequency, and which color of light that gets bent the most and therefore has the highest frequency. Which of the following explanations about the observed model is correct? The phenomenon being observed is diffraction, the red color is bent the least and has the lowest frequency, and the violet color is bent the most and has the highest frequency.

The phenomenon being observed is diffraction, the violet color is bent the least and has the lowest frequency, and the red color is bent the most and has the highest frequency
The phenomenon being observed is refraction, the red color is bent the least and has the lowest frequency, and the violet color is bent the most and has the highest frequency.

s the environmental science is a broader field that incorporates many elements of earth and life sciences, whereas ecology is usually more focused on how organisms interact with each other and their surroundings, and often on a very specific population of living things. soo yea

explanation:

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.
