💁‍♀️ 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?

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?

[@bhawnamehta2261]

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!!

[@scisarah3770]

I like this one!!

[@louielouie9502]

I used to loathe math as a kid. That was before I began interest in discovering which synchronicities act as a direct map to the laws governing universal patterns of creation. The electromagnetic spectrum is a great way to start looking into how to solve for other energetic equations pertaining to how the rest of the universe is structured. It sounds far more complicated than it actually is. Maybe we can work together for making coloring books for this stuff some day. ,😊

can anyone explain to me how to compute 1s^-1 on the calculator

[@TheZafootz]

does anyone know how she got 10^-19 at 25:35? im so confused on where that 19 came from.. :(

[@michellecampa9850]

Do you know at the minute 16:47 she got 1.025x10^8 s^-1 and why i got 1.025x10^5 ???

[@scisarah3770]

Hello! I am sorry I am a bit late but I am assuming this may be a calculator issue? When I first started chemistry I would have typed that like (6.626) x (10^-34) etc... Make sure you aren't doing this! There is an exponent key on most scientific calculators (EXP) which is how you should enter the equation. Granted you are doing this I believe you should get 10^-19 as an exponent. Removing the calculator altogether you can look at it logistically. I am assuming you know that you can subtract exponents in the numerator from those in the denominator, so, if I were to add the numerator exponents (-34 + 8) that would equal -26. I now can *subtract* that from the denominator's exponent, so (-26 - -7). The double subtraction symbols reduce to an addition symbol, and the ultimate exponent becomes (-26 + 7) = -19. That is a bit difficult to convey in a text medium but I hope you understand! If you need any further help let me know! I wish you well! :)

[@jwunel]

@@michellecampa9850 I don't know if anyone answered you yet, but I figured it out, 102,500,000 represented in scientific notation is 1.025, to convert 102,500,000 to scientific notation we have to keep moving the decimal until there is only one non-zero digit to the left of the decimal point, in that case it would be 1, and if you count how many places we had to move it would be 8, so in this case its 1.025 and we moved 8 places, hope that helps!!

[@kentonewing1195]

@@michellecampa9850 1.025 x 10^6 is the conversion which equals 102,500,000 or 1.025 x 10^8 because you move the decimal 8 places to the left to make 1.025 s-1

is it possible to have a a digital calculator on the screen share. I add up all the numbers and still get a different answer or even though you lay it out, I still don't know how you got the answer. I don't know how to use my calculator. Can we see you plug it in?

At around 1:29, when talking about the first formula... you say that it helps to determine the frequency when given the wavelength and vice versa when given the wavelength and asked to find the frequency..... I assume you meant to say that when given the frequency we can find the wavelength? Should probably throw an edit on there for us confused folks trying to learn. Those are the same thing lol. 😂😂
