Speed of Light, Frequency, and Wavelength Calculations - Chemistry Practice Problems

Published 2017-09-23
This chemistry video tutorial explains how to solve problems involving the speed of light, wavelength, and frequency of a photon. It also explains how to convert wavelength from m to um and nm to m.

    It's unreal how incredibly valuable these videos are and have been, especially over the last two years. You have not gotten anywhere near the recognition you deserve for putting so many hours into making these subjects accessible for everyone.

    0:20 - Wavelength of a photon that has Frequency 2:50 - Frequency of photon that has Wavelength 4:13 - Frequency of photon that has Wavelength 5:40 - Wavelength of photon that has Frequency 6:55 - What happens to Wavelength as Photon Frequency increases? 7:37 - What is Frequency of photon with Energy 8:59 - Wavelength of a photon with Energy

    i’m literally watching this taking my test and i have 8 mins left to finish
  • @watakashe6072
    my teacher makes things unnecessarily complicated in a long lesson, this explained the concept in 10 minutes and I aced the exam, you're literally a god
  • @TresorOertel
    I have a quiz in 5 minutes wish me luck y'all Edit: A year later I find myself taking O chem II over the summer and am currently dying wish me luck
  • For anyone who is stuck on how the they get 10^14 from 3*10^8/350*10^-9. Do 3/350, the answer is 8.57* 10^-3. then do 8-(-9)=10^17. simply add them 8.57*10^-3 + 10^17= 8.57*10^14.

    one thing I learned from this video my teacher doesn't know what she's saying
  • @raintaro
    I love this guy I was in class the teacher asked me how I’m going to figure out these light problems for tomorrow and I said the Organic Chemistry Tutor and everyone in my class started laughing😂
  • @ryantroiano166
    Taking chemistry online is insane. Thanks for making it all make sense to a visual learner like myself!
  • Your videos have made it so much easier for me to understand chemistry. I have one request. I can barely hear your soft spoken voice even when I turn my volume all the up on my laptop. can you maybe turn up your microphone so I can hear you louder? thank again.
  • @dania.taylor11
    Super helpful!😭 I pray there be continuous blessings for you and your family for generations!🙏🏽
  • @korumo5004
    I don't learn from my professors. Instead, I learn from this channel. Thank you!
  • @dacookie_1473
    Thank you so much!!! My teacher didn’t bother to go over it twice, now I understand it ty
  • @KBDarell
    Your videos always clearly explain the ambiguous steps that I need spelled out! I'm so grateful for you and for these videos, I really appreciate them!!
  • Professor Organic Chemistry Tutor ,thank you for a solid analysis and explanation of the Speed of Light, Frequency, and Wavelength in General and AP Chemistry. Chemistry is used in all walks and phases of life on planet earth. Frequencies and Wavelengths are well known concepts in radio technology. This is an error free video/lecture on YouTube TV with the Organic Chemistry Tutor.
  • thank you!! as an absolute dunce when it comes to chemistry, i actually understand this now:) also, a lot of people have been struggling with the exponents, and they might be using their calculators wrong. i was too, but when i learned this suddenly i could do math. so for the first problem, 3 x 10^8 / 2.5 x 10^12, you do not want to put it in the calculator like this. instead of putting x 10^8, click the *2nd* button (the blue one on the far left). then click the *x^-1* button. it will look like 3E. now, just add the 8. repeat this step, replacing all tens with es, which should get you 3E8 / 2.5E12. this will get you 1.2 x 10^-4m

    This is incredible. This video, just like most of the others ive watched here has explained more in 11 min than my text book or unresponsive "mentor".
