What is The speed of a wave is 65 m/s. If the wavelength is .8 m what is the
frequency of the wave? *

Explanation:

If

v

is the speed,

λ

is the wavelength and the frequency

f

of a wave is given by:

f

=

v

λ

Here

v

=

65

m

s

,

λ

=

0.8

m

⇒

f

=

65

0.8

=

81.25

H

z

Hence, the frequency of the given wave is

81.25

H

z

.

"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.
