<p>can anybody help me with these problems?
its on atomic energy calculation.</p>

<h1>2 is part of problem 1.</h1>

<ol>
<li><p>Infrared radiation has wavelengths ranging
from about 800 nm to 1 mm. What is the
frequency of radiation of wavelength 870 nm?</p></li>
<li><p>Microwaves, such as those used for radar and
to heat food in a microwave oven, have wave-
lengths greater than about 3 mm. What
is the frequency of radiation of wavelength
6.35 mm?</p></li>
</ol>

<p>thank you in advance!</p>

<p>for number one and two, use the formula c=frequency times wavelength. Make sure to convert length to meters.</p>
