We sneak in and here's your smoke to use your

00:04

brought to you by amplitude it's like attitude but for

00:08

amps all right two waves travel toward each other on

00:11

the same axis The first wave has an amplitude of

00:14

four millimeters and the second wave has an amplitude of

00:17

five millimeters what's the largest possible amplitude the resulting wave

00:23

can have And here the potential answers One four five

00:26

nine waves crashing together Woo this could only mean one

00:30

thing Waffles No wait Not waffles All right we're hungry

00:34

And this question well we're dealing with super position So

00:37

all right moving on When waves collide they show super

00:41

position Well superposition means that the waves will combine at

00:44

the moment of collision and the amplitude of this combined

00:46

wave will equal the net amplitude of the waves have

00:49

collided Or to put it more simply to find the

00:52

largest possible amplitude of the combined wave we just add

00:55

up the amplitude of the two waves involved after tackling

00:58

some of these questions while doing simple addition feels like

01:01

putting on our favorite t shirt Easy peasy and what's

01:04

wrong with a dora the explorer t shirt way like

01:06

this and in this question the additions pretty easy five

01:10

millimeters plus four millimeters in california at least equals nine

01:14

millimeters that's the maximum possible amplitude for the wave formed

01:17

by this collision So the right answer is deep Now

01:20

If one wave was positive and the other negative well

01:24

then the waves would cancel each other out at least

01:26

partially So the net amplitude would be much smaller from

01:29

that situation We have to do subtraction which is a

01:32

little harder than edition but well we think we can

01:34

handle it Remember those number lines from third grade Well

01:37

in this case we're dealing with two positive waves so

01:39

we just adam up time for a jam sesh We

01:42

might need a new amp Uh this one seems totally 00:01:44.825 --> [endTime] over us
