Will fan and medal!!! The frequency of a given region of the electromagnetic spectrum ranges from 4 × 10¹Ê to 7.5 × 10¹Ê Hz. The speed of light is 2.998 × 10§ m/s. Which waves are found in this region? microwaves infrared waves visible light ultraviolet reays

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

oh ok
anonymous
  • anonymous
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
MTALHAHASSAN2
  • MTALHAHASSAN2
which grade question is it
anonymous
  • anonymous
I think 12th grade, do you know someone who might know?

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.

I still have no clue what it would be.. @Shalante

  • anonymous
What is number for speed of light?
anonymous
  • anonymous
2.998 × 10§ m/s
anonymous
  • anonymous
which is?
anonymous
  • anonymous
How you would insert that variable in a scientific calculator?
anonymous
  • anonymous
29.88?
anonymous
  • anonymous
Read my explanation.
anonymous
  • anonymous
I did I don;t know how to do that so it doesn't help me. I barely understood it
anonymous
  • anonymous
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)
anonymous
  • anonymous
Try to focus and reread it several times carefully
anonymous
  • anonymous
Also, if you are asking for help, ask which part that you do not understand one at a time chronologically.
anonymous
  • anonymous
The numbers them selves confuse me, I don't know how to set up my equation I guess you could say
anonymous
  • anonymous
Ah, I see 3.00 x 10^8=\[3.00\times10^8\] So what are the number for speed of light and frequency?
anonymous
  • anonymous
Well when I multiplied what they they give me 300,000,000
anonymous
  • anonymous
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.
anonymous
  • anonymous
Yes 300,000,000 is normal number for this question.
anonymous
  • anonymous
....no I'm horrible at math.... like horribly horrible
anonymous
  • anonymous
So from there where would we go?
anonymous
  • anonymous
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)
anonymous
  • anonymous
Frequency?
anonymous
  • anonymous
What about frequency?
anonymous
  • anonymous
Reread your problem several times carefully to get a better understanding of what I am saying
anonymous
  • anonymous
Sorry my computer died yesterday and is 300,000,000 the wavelength?

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?
anonymous
  • anonymous
The ans is visible light...
anonymous
  • anonymous
not 100% sure though
anonymous
  • anonymous
Thank you, it was right. Could you show me how you got that?
anonymous
  • anonymous
All I used was the given frequency.
anonymous
  • anonymous
Each part of the spectrum has a name and frequency. Like Gamma rays they have a frequency of 3 time 10^19 hz
anonymous
  • anonymous
Wavelength less than one nm if you wanted t know.
anonymous
  • anonymous
to*
anonymous
  • anonymous
Still in doubt,@WhatEven ?
anonymous
  • anonymous
No I understand a little better now. Could you help with one more?
