I know it's not microwaves, my teacher told me that much, but I'm at a loss for the rest.
Your exponential numbers are not clear! If you use the formula wavelength = speed of light / frequency and work out the wavelengths for both of your frequencies and compare with the approximate values given below, you will be able to answer this question. microwaves 1 x 10^-3m - 1m infrared 1 x 10^-3m - 1 x 10^-6m visible 1 x 10^-6m - 1 x 10^-7m UV 1 x 10^-8 - 1 x 10^-9m. Also, have a look at some of the electromagnetic images on the internet e.g yahoo.images! You will find this v.useful!
I found this on google 5 different times and it wasn't helpful >.< I don;t understand how to do this and I can't make it anymore clear, it is a question from my quiz I copied it word for word, I have to answer using the information they gave me
So no ideas? Because I don't know what to do and if I don't pass my quiz it'll bring my whole grade down
which grade question is it
I think 12th grade, do you know someone who might know?
ok let me find anyone then
i will advice you to try this website they are goona help you faster over there www.peeranswer.com
You know that speed of light=(frequency)(wavelength) All those waves in the choices all have different wavelength. Frequency is in hertz Speed of light is 3.00 x 10^8 You were given frequency and speed of light. Now find the wavelength. If the wavelength has the same exponent in scientific notation to one of the waves, then it is that one.
What is number for speed of light?
2.998 × 10§ m/s
How you would insert that variable in a scientific calculator?
Read my explanation.
I did I don;t know how to do that so it doesn't help me. I barely understood it
All you do is read in my explanation to know the number for speed of light. If you cant do that, then I dont know. It is going to take a while. (A huge waste of time)
Try to focus and reread it several times carefully
Also, if you are asking for help, ask which part that you do not understand one at a time chronologically.
The numbers them selves confuse me, I don't know how to set up my equation I guess you could say
Ah, I see 3.00 x 10^8=\[3.00\times10^8\] So what are the number for speed of light and frequency?
Well when I multiplied what they they give me 300,000,000
Hertz can be written as hz Did you pass Algebra 1? Since you are in chemistry and are that far, I assumed you have a good math background.
Yes 300,000,000 is normal number for this question.
....no I'm horrible at math.... like horribly horrible
So from there where would we go?
Speed of light=(frequency)(wavelength) Speed of light is in the unit m/s Wavelength is in the unit m Frequency is in hertz or hz Which of those are given in the problem. (meaning they have a number)
What about frequency?
Reread your problem several times carefully to get a better understanding of what I am saying
Sorry my computer died yesterday and is 300,000,000 the wavelength?
Well I never got to finish talking with him and now he's off line and I'm stuck

I'm still confused and my teacher is getting mad at me. Any way you could let me know what it is then explain how you got that?
The ans is visible light...
not 100% sure though
Thank you, it was right. Could you show me how you got that?
All I used was the given frequency.
Each part of the spectrum has a name and frequency. Like Gamma rays they have a frequency of 3 time 10^19 hz
Wavelength less than one nm if you wanted t know.
No I understand a little better now. Could you help with one more?
