Covalent bonds in a molecule absorb radiation in the IR region and vibrate at characteristic frequencies. (a) A molecular vibration absorbs radiation of wavelength 194 μm. What frequency (in s−1) corresponds to that wavelength? Enter your answer in scientific notation. × 10 s−1 (b) A molecular vibration has a frequency of vibration of 1.409 × 1013 Hz. What wavelength (in μm) corresponds to that frequency?

(a) Frequency will be equal to

(b) Wavelength will be equal to      

Explanation:

Velocity of light

(A) We have given wavelength of light

We have to find frequency corresponding to this wavelength

We know that velocity of light is equal to

(b) We have given frequency of vibration

We have to find wavelength corresponding to this frequency

We know that velocity of light is equal to

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

its a 5.5 n
