Learn a SIMPLE way to
Learn a SIMPLE way to calculate the frequency of a specific wavelength of electromagnetic radiation.
Sorry! At 2:59 I made a human mistake. I said one billion nm is equal to 1 m, but I wrote 1,000,000 which is only a million. This mistake didn't alter the answer, it was just a human writing error.
Gyyyyyrl please upgrade your calculator to a TI-84 Plus CE. ???
You got everything right except you put 1 million in the box instead of 1 billion. Also 1nm =1*10^-9m
You just saved my grade. Thank you so much.
I understanded everything clearly thank you for that but at 4:59 it was
7.3170 into 10*14 hertz
How does the 10 raise to power 14 comes, and how to slove the 2 last step to get 10 raise to power 14 , im actually in class 10 i but i didn't understand how that raise to power 14 came . can you please help me out ,and in our school they only allow us to use simple calculator not scientific one!!
Help for me
This chemistry video
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.

in the one with x10^8 and x10^-9 how did the answer get to x10^14?
What is the wavelength of the UV light with a frequency of 1.07 x 10^15 Hz?
This is better than the textbook that's supposed to teach me -__-
i love u thank u omg

Dr. Elizabeth Plourde discusses the damage electromagnetic frequencies can cause in the body, even down to the cellular level. Find out what conditions may be caused by this kind of pollution. She also discusses how she was affected by EMFs!
The minute this lady mentioned autistic children, I immediately lost respect fir anything else that came out if her mouth...
This systematic review is basically some very smart people reading and analyzing the works of houndrens of other scientists on this issue. The topic is higely researched, and the conclusion is this: "The overwhelming consensus of these reviews is that present evidence does not show the existence of health hazards from exposures below present limits (ICNIRP or IEEE)."
(Foster, K. R., Moulder, J. E. Wi-Fi and Health : Review of Current Status of Research. Health Physics, 2013, 561-575)
One instance of whatever this woman claim, is nothing and frankly disrespectful to the large scientific studies out there on this topic.
So how are we going to escape it. By eating a bullet?
I think you have a good presentation, an I totally agree with the research , I feel it amplifies the conditions of illnesses, an turns into chronic , so I totally agree that EMF EXPOSURE DETERIATES HUMANS QUALITY OF LIFE, BECAUSE IT BREAKS DOWN OUR DNA ON molecular levels, sloooowly.
It's one thing to know about it and another thing to do anything about it...what do we the people do Besides complain about it ? I'm sure it will take all of us to stand together, if that's even possible
