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

    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

    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.

    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)

    Ah, I see 3.00 x 10^8=\[3.00\times10^8\] So what are the number for speed of light and frequency?

    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.

    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)

    Each part of the spectrum has a name and frequency. Like Gamma rays they have a frequency of 3 time 10^19 hz
