A mercury lamp emits radiation with a wavelength of 4.36 X 10^-7 m. (a) What is the wavelength of this radiation in centimeters? (b) In what region of the electromagnetic spectrum is this radiation? (c) Calculate the frequency of this radiation.

Question

anonymous · Answer

for part a, it is just a simple conversion of m to cm. so multiply by 100
b. look it up online
c. can't help

anonymous · Answer

so for part a) i got 6.9x10^6 m; how to convert to cm?

how did you get that for part a)?

it's wrong. 

it's just a conversion; 1 m = 100 cm 


b) Look it up online

for c) use:  $\lambda*\nu=c$

actually it was right. i looked it up online in the teachers edition book @aaronq

"A mercury lamp emits radiation with a wavelength of 4.36 X 10^-7 m. (a) What is the wavelength of this radiation in centimeters?"

you said "6.9x10^6 m"

it can't be a different number.

1 m = 100 cm

 $4.36 *10^{-7} m=4.36 *10^{-7} *\dfrac{100~cm}{1~m}=4.36 *10^{-5}~cm$
