Finding Wavelength, Frequency, Velocity Using de Broglie's Equation | Study Chemistry With Us

In this video, I'll explain how to properly use de Broglie's equation to find the wavelength and frequency. I'll also go over a really important unit conversion you need to know for this section.

🙌 This was my go-to homework help when I was in school. Chegg Study is one of my favorites.

📚 I made the mistake of buying all of my textbooks, I wish I had the option of renting them. Thankfully you do, with Chegg Textbook Rentals.

💁‍♀️ HI I'M MELISSA MARIBEL
I help students pass Chemistry and Organic Chemistry. I used to struggle with this subject, so when I finally graduated with a bachelor's degree in Chemistry, I became a tutor so that you wouldn't have to struggle like I did. I know that with the right help, YOU CAN LEARN ANYTHING!

DISCLAIMER: Some links in the description are affiliate links, which means that if you buy from those links, I’ll receive a small commission. This helps support the channel and allows me to continue making videos like this. Thanks for the support!

Questions Covered:
1) The speed of an electron is 1.85 x 10^7 m/s. Calculate the wavelength. Calculate the frequency.
2) The speed of an electron is 2.63 x 10^6 m/s. What is the wavelength?

Melissa Maribel!!!!😀 you should put a camera on your calculator from a different angle while you are using it so everyone can see how you are punching in the numbers. Sometimes TIs are such a pain.

[kalynncarter]

a calculator video would be wonderful, I was having trouble too! thanks for spending time to go over that problem. I wrote down what to type into my calculator for next time.

[trevorspeer]

Thank you. Thank you. Thank you. The units were confusing me. THANK YOU for going into detail! You saved my sanity.

[azuzena]

going over this in physics... THANK U SO MUCH

As a detail, in 9:45, you can't find the "frequency" of an electron using the speed of light. That only works for EM waves where the speed of the wave is the speed of light. The frequency would be determined by E = h*f, where E is the energy of the particle and h is Planck's constant.

watched your previous videos and they really helped me! Thank you so much!

Hi been following your channel for a while and helped me alot like alot.love from india and hoping live stream too :)

[n.delgado]

i got it thank you taking chem online due to covid and this has been so helpful!! thank you thank you

[iambananahannah]

Hi Melissa! Your videos have been so so helpful and I'm learning so much. I'm getting myself ready for Chemistry for the winter semester. Anyway, just curious where I can find the rest of the answers for the problem questions in this video. Please and thank you!

[tenzindikila]

Thank you, I really appreciate what you doing... Final exam is coming up this Monday 😧😫

[donyaalkhamis]

you should do a series where you help a I'm currently studying for my final this Tuesday, and I think I'm gonna cry. trying to go over everything last min is extremely hard.

What if you are not given mass? in a problem i am asked to calculate the mass of the subatomic particle.

[imanismith]

Why does my calculator give values such as 0.0763358 instead of 7.63*10

[trinitybreanne]

Where does the -11 come from in the first answer? I understand the 3.93 but not the -11
