How to Find the Wavelength, Frequency, Energy and Photons | Study Chemistry With Us

I'll teach you how to calculate the wavelength, frequency, energy, number of photons, energy of mole of photons and more. We'll go over how to properly use each formula used in the electromagnetic spectrum and of course, everything is step by step.

📚 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 in this Video:
1) Calculate the energy of X-rays with a wavelength of 15.0 nm.
2) What is the wavelength in meters of an FM radio wave with a frequency of 102.5 MHz?
3) If the wavelength of a photon is 552 nm. What is the energy of one mole of photons?
4) How many photons are contained in a flash of green light (525 nm) that contains 189 kJ of energy?

I love this format. Makes learning so much more bearable.

[gotsparkles]

I need to start watching these videos LONG before i have to take the exam LOL

[Croriam]

Watching this vid at 1.5x speed before a test. Boy i sure do love depression

[sincerelyashby]

I loved it ! I just finished doing all the problems with you guys and to be honest I enjoyed it!

[haileyleon_]

you have SAVED ME for my chem test thank you so much!

[cosmicenigma]

my teacher literally showed these formulas; talked about electromagnetic waves and the spectrum; then never touched them again and now she's saying we should know it for our final :). Melissa, you're a literal angel

[jacobwestfall]

Struggling through this with another student makes this more relatable. really enjoy (I guess you can call it that) this format.

[shadoshi]

Thank you for all showing us how to solve Photon energy, you always make this easy to understand. Thank you very much for your time to help students from College and High School! It was fun doing all these problems!

[misselle]

I am starting all online chem April 13th and I’m so nervous because I am HORRIBLE at math and everything that has to do with it. I can relate to Melissa so much lol. Thank you for these videos! I am looking forward to watching your videos when I start my class. I also bought your Flashcards so hopefully I can pass my class 👍🏻

[MivanBaldwin]

Ms. Maribel, if it wasn't for you teaching Melissa I am not sure this semester would have gone so smooth. Thank you so very much!

[rafaeljaramillo]

You are a great teacher!! God bless you , it's notorious your passion for teaching . You are an awesome pillar to learn from, thank you!!

[gaoxoxo]

You are saving my chemistry grade! Thank you very much!

[alexanderpinkerton]

wow you are such an incredible teacher, the way I'm learning this so quickly, thank you for doing what you do<3

[lle]

I have an exam on Monday on everything you're covering in this series. Thank for doing this.

[laural]

can you explain how 10 e-34 and 10-e8 give you 10 e-17 for question number 1?

[jpeper]

Thank you Melissa Maribel. You make it easy.

[bhawnamehta]

I made a mnemonic to remember that c= lambda x frequency (v) formula


Cathine Likes Vulpix. where, V= frequency and L= lambda which is the wavelength


To all of them who are confused by that Vulpix thing. It's a pokemon. Gotta catch'em all!!

[kristymartes]

okay so I see I'm not the only one getting to the power of -33 when find wavelength of 15.00 nm. Does anyone know why this is?

[mirandapawlak]

I wish I could hug you lol !! All your videos are extremely helpful, don't know what I would do without them!

[aysamcclain]

how are you getting the -17 exponent, i get the 1.3252 but I am getting -30 exponent on step 2 the first equation
