Question

What is the wavelength (meters) and type of wave for frequency, 1 × 107? PLEASE HELP

Answer 1

wavelength = wave speed / frequency

you got frequency, speed of light is 'c' = 3 x 10^8 m/sec. You can find wavelength now, I guess.


For the type of wave, match wavelength or frequency with the spectrum series.

Answer 2

I'm still confused. What do i do?

Answer 3

I listed the formula above. Feed data, cross-multiply and calculate.

Answer 4

I wrote my problem wrong. 1 X 10^7.. Sorry . But um, could you write an example problem and show me step by step? (this is my weak subject)

Answer 5

Well, okay I 'll give you an example.
suppose,
x = yz
given, x = 12 , y=4. Can you find 'z'?

Answer 6

z = 3?

Answer 7

ok, so now, your formula is lambda = c/f where you know c (3 * 10^8) and f (1 * 10^7). What's lambda going to be?

Answer 8

if my frequency was 5 * 10^6, my wavelength would be (3 * 10^8)/(5 * 10^6) = 60

Answer 9

30?

Answer 10

Correct!

Answer 11

That's all that i have to do? That's easy.. Thank you.
