Calculating wavelength of a wave

In this video, we learn how to calculate the wavelength of a light wave from a known wave frequency. Update: Units would be in meters not Hz.

It helped me a lot! ! ! Thank You Sir! ! ! 😊

[@ScienceBeetle]

You are very welcome. Glad we could help. Happy Learning.

What if your answer had the decimal in a different place

[@Nitusingh-di7hq]

Sir thanks for this question

[@ConsciouslyEvolving]

If the hz canceled itself out wouldn't it be meters?

[@NinjaAceRBLX]

Its m, he just made a mistake, he said so in a reply

[@kingryanruiz1520]

why is the answer in Hz if what we are looking for is the wavelength?

[@ScienceBeetle]

Hello Ryan, The answer would be in meters. Hz was inadvertently written. I'll update the video and make the correction. Thanks for letting us know. Blessings.

Sir how to Calculate the wavelength if the frequency is 4.909x10-¹⁹ J ?

[@ScienceBeetle]

Hello ZM, thanks for the question. At first glance the units of "J" for the stated frequency should be "hz" for hertz. Given this change, to calculate the wavelength, we take the speed of light (3.0E8 m/s) and divide it by the stated frequency (4.909E-19 Hz). This should give you a wavelength of 6.11E26 meters. Happy Learning!

what is the wavelength of a wave with a frequency of 3x109 Hz?

[@ScienceBeetle]

Hello Jm, use the equation "C= wavelength * frequency." Divide C by the frequency and you should get "3.0E8 / 3.0 E9" which is 1.0E-1 wavelength.

How could the answer is Hz instead of m, as far as I know the unit of wavelength is m 😅, btw tnx

[@Yuki_1123]

Use m

[@ScienceBeetle]

Hello, the unit is "m." the Hertz unit of "hz" was written inadvertently. Thanks for highlighting this, we will update the video.

What is the wavelength of a wave with frequency of 4.28 GHz?

[@ScienceBeetle]

Hello Diya, The process is the same as in the video, but you will first need to convert the Gigahertz (GHz) to Hertz (Hz). The conversion is 1E9 hertz per giga so take 4.28 and multiply it by the 1E9, then plug the value into the wavelength equation with the speed of light to arrive at your answer. Should be about 7.00E-2 meters. Best wishes!

what happened to the 10 to the 8 and 10 to the 5th?

[@ScienceBeetle]

Hello. When you plug the values into the calculator they 10E8 and the 10E5 end cancelling each other by way of subtraction of exponents. If we just look at the "8" and the "5" we see that 8 minus 5 will give us 3. This means our answer will have significant digits above 1. Looking at the answer, we see that 870. does in fact have 3 significant figures. Best wishes.

Can you solve this problem for me What is the frequency of radio waves with wavelength of 3 X 10² m plssss

[@ScienceBeetle]

Hello, You would use the C = wavelength * freq equation. Derive the new equation for freq (f = C / wavelength), plug the values in and your freq. should be 1E6 hz.

[@boyetlami7231]

damn u didn't show how u got the answer

[@ScienceBeetle]

I'm sorry the process was not shown for you. I'll generate another example and include it for your consideration. Thanks for letting me know.

[@Hans_Ulrich]

Why do you sound like joe biden💀

[@ScienceBeetle]

Did not know I sounded like an American President. I'll take the comment in a positive way. In either case, glad I could help with the videos. Happy Learning.
