What the wavelength of a microwave whose frequency is 2.75 * 10 ^ 10 ? Use c=3.00*10^ 8 m/s

0.011 m

Explanation:

From the question,

The speed of a moving wave is related as

c = λf Equation 1

Where c = speed of the wave, λ = wave length, f = frequency.

make λ the subject of equation in equation 1 above

λ = c/f Equation 2

Given: c = 3.0×10⁸ m/s, f = 2.75×10¹⁰ Hz

Substitute theses values into equation 2

λ = 3.0×10⁸/(2.75×10¹⁰)

λ =

1.09 * 10^-2

Explanation:

I got it right when I did it. This is the right answer. I tried the other answer and was wrong that the other guy posted.

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
