1. Light near the middle of the ultraviolet region of the electromagnetic spectrum
has a frequency of 2.73 X 1016 s-1
a.
What is the wavelength of this radiation in meters (m)?
b.
What is the energy associated with this radiation in kcal?

Explanation:

Given that,

The frequency of electromagnetic spectrum is

(A) Let the wavelength of this radiation is . We know that,

So, the wavelength of this radiation is .

(B) Let E is the energy associated with this radiation. Energy of an electromagnetic radiation is given by :

h is Planck's constant

1 kcal = 4184 J

It means,

Hence, this is the required solution.

4

explanation:

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
