If the speed of a wave doubles while the frequency remains the same, what happens to the wavelength?

What the Bush is asking if the speed off a wave devils while the women remains the same. What happens to the president's So the frequency is given as velocity upon Landa Now the new frequency. It says that the density is trees drives right when a city is doubled are the speeders Dublin said to be by Lambda, which is a record two through times frequency. So what we can say is the new frequency we concede doubles when screened devils You know what, so this

Kilograms. So we're gonna be looking at Problem 36. And the question sees is the frequency of a period of wave is cut in half. Well, the speed remains the same. What happens to the we've learned So looking over calling rather the former for concludes in the speed away. We have Visa quote too. If lumber. Yeah. So now you see the questions they do frequency or the pretty quick is courting. How so? If becomes if what? Sue? Well, dispute remains the same. So v. Satirical TV. What happens to the Waveland? So what happens to the Waveland? And so since V remains the same, we can see flum dough. Is it quote too? The the half in off the frequency, which is of over two. So this is the question, and we're gonna be looking for this going quotas if I'm the one. So this would tell us Well, oh, change would help on what change would help it to the wavelength when the frequencies How so? So when this are making Lambda one to serve it off from what we have longer one on the one of his acquittal. Too much clever f longer because those course once blood? Yes. So making them the ones of the formal available. I'm the one. The quote to a mumbo to a little boy. So if and so one, the one which is on new Lambo or new wave lands when the frequencies off is to longer. So oh, a new Waveland is multiplied by two.

So were asked about a wave and the frequency of the wave is doubled. What happens to the wavelength? As a result, in what happens to the speed of that wave, we're gonna derived of the speed of a wave. We know that speed is the distance or the displacement traveled per unit time. We have to choose our values carefully to come up with an equation. So we know a few things from our previous videos the period, which is the time it takes for one cycle. And also we have the wavelength, which is the length of a cycle cycle. Time is units of and seconds. And we went through this and units off years. So if we were to have a wave pass, um, or traverse for one period painful period, that means there would be one full cycle that travels. And in one full cycle there's a length of lambda that is passed. So for this equation, we can write Lambda as our displacement for our distance traveled and the period as the time traveled. This is a correct expression. We know also that T r. The frequency is one over tea. The frequency is the in first of the period. So this equation can be written as Lambda F the wavelength times. The frequency is equal to the speed of the wave. Now, the speed of the wave is constant in every medium, speed is constant. You have to remember this, uh, for any medium, you cannot change the speed in which a wave moves for air, for example. For example, it's about 343 leaders per second, and you cannot change the speed of in which the wave travels. Will always travel at this, that at this speed and 43 years per second. So the question says that our wavelength will change as a result of the frequency changes. So if our frequency doubles have a frequency, doubles what that past happened to our wavelength in order to keep the speed side the same. Well, the answer is that it would be halved. It would be halved because 1/2 times two is one and one times its value is the same with the constant. So that would allow our speed to remain constant in this situation here. So our wavelength is is halved because of our, uh, frequency being doubled and the speed, which is always constant in the medium, does not change. So that is our answers. Here we will say the wavelength lambda is halved and speed, uh, is constant. Okay, so that's the answers for these. These questions is that a wavelength is have as a result of the frequency being doubled, and the frequency is constant because it's constant in any, uh, medium.

For God s over problem 38. The questions is will happen to the Waveland or periodic wave, even put the speed of the wave and frequency our courts in hell. I'm so using the marginal figures we have V is equal to, if long ago. And so using the water freezes mean the quotes or six frequencies 1/4 to 3 and longer. Is that going to some of the questions? Accidents will happen. What would happen if I put the speed and frequency or quit? And how so? I'm so grateful. Lambda we have longer is equal to Marine. Well, so you Oh, Speed V is sick with his hopes. Will do anybody to What about frequencies? Three You want to buy? So so this should give us to me. What a boy one for? For So do you know what about 15 is too. So if the frequency and the speed Babeu's hope Woods hopes the we've lands remain the same. So the answer to this question is we've lend to remains the same. So rebloom
