3. In each of the following pairs, circle the form of radiation with the LOWER ENERGY (energy is directly related to frequency): a. red light or blue light
b. microwaves or radio waves
c. infrared radiation or red light
d. gamma rays or UV radiation
e. yellow light or green light
f. x-rays or gamma rays
g. UV radiation or violet light
h. AM radio waves or FM radio waves

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
