Calculate the de Broglie wavelength for each of the following. a. an electron with a velocity $10 . \%$ of the speed of light b. a tennis ball $(55 \mathrm{g})$ served at $35 \mathrm{m} / \mathrm{s}(\sim 80 \mathrm{mi} / \mathrm{h})$

In this question, we want to calculate the broad anyway flank of uh moving ball. Okay, so to do this can be using lambda. It goes to H. O. P. Which is H over M. V. Okay, So the we're playing, the body were playing is age over and we just put in the numbers demands 0.15 kg. The speed is 40 m per second And the answer is 1.11 times 10 to the power negative 34 m. Okay, So the significance of the result. Okay, The abruptly with flame is so small, um, that to be detected by human eye. Mm So, um, it is uh, so we are unable to observe the week nature or the way behavior off every day of moving objects uh, in our daily life. Okay. Yes, because the plane is so small that we cannot see it. Okay, so this is the significance. Okay, So small and unable to observe. Right? And that's all for this question.

In this question. Okay. Yeah. Given to objects. So baseball. Uh 0.1 G. K. Moving ads. 100 master our. And then we are given the individual spaceship. Okay. Which has a huge uh 2050 kg. Okay then moving at 125,000. Just uh so in this question um probably want to find out they probably were planning to fall a bit that they probably were planning for a job. Okay so solution. Okay so this question is about the broadly we plan. So we're using uh like H. P. Which is H. Over and be okay. And then uh $100 per hour is equal to 44.7 with us for a second. Okay So run down the the different everything of the bar issue of Mv. Okay. 11 numbers. Okay. And you compare this to be okay for eight times 10 to the negative that evolved leaders. Okay so this is the answer of a. Okay then be okay. We repeat the same procedure for wager. Okay so uh the speed is 225,000. Uh could only does per hour. Okay, so to cover this to uh meters per second. Okay. You need to multiply by 1000 because one p.m. Is equal to 1000 m and then what our is equal to 3600 seconds. Okay? So when you do this calculation, uh can you get uh 34722? Who does per second? Okay then. Uh every playing with the Malaysia is H over M. V. So put in the numbers. Okay then you get 7.64 times 10 to the negative 41 because okay, so this is the answer for party and that's all for this question.

This question you are given to objects. Okay. So we have baseball which is their 0.1 PG. Okay. Moving ads. 100 miles per agua. Now we also have the Voyager space spaceship. Okay. And then there's this 250 kg. Keep moving at 125,000. You don't need this for our you want to find out. They brought me replay for each object. Okay, so to solve this question, okay, we know that they brought the refrain lambda is H. Overpay which is H over M. V. Okay. And then we know that 100 MPH is equal to 45 27 m per second. Okay, so we can calculate uh he brought me be playing off the ball. Mhm. Just put in the values and you calculate this. We've learned to be 1.48 times 10 to the negative. 34. Yes. Okay. So this is the answer for a then. Probably we just repeat the same steps by this time. We need to convert 12500 125,000 kilometers per hour to meters per second. So you convert km into metres, which is 1000 m and then one hour is 2600 seconds. So when you do this, Okay. Mhm. And you get 347 to 2, you guys cook second. So the you brought me the name of the original spaceship? Yes. Asia M B. Mhm I am. It's 2053 years. 347 to 2. Okay. You get 7.64 times 10 to the maybe the 41 m. So this is uh probably very plain of the will you join a spaceship? And that's all. What is question?

Okay, so does chapter 37 problem, Cordy. So it says calculate the wavelength of is Europe to three kilogram bowl. Traveling at eight plus is mass. And this traveling at a speed of 0.1 meters per second. Okay, so we can excuse equation 37 7 for the liberal labeling. Things was given as the wavelength is h over the momentum. And since this is moving very slowly, then you don't have to use relativistic momentum. Misuse classical with 10 times V. So we just plug this in 6.63 times to have a negative 34 cool seconds over 0.23 kilograms times the report one years per second. So we can already see that this is gonna be very tiny. And indeed it is 2.9 times 10 to the negative 32 years. Try and imagine something that small is pretty hard, huh? Yeah, that's it for this problem.
