Hey, how's it going here? Were given the frequency of 3.55 times 10 to the power of 17 hurts. And we need to find the energy and jewels here. We need equation that relates frequency with energy. The only one I can think of this energy equal supplies constant times, you. Which is the frequency here. I've already indicated on the right that the plank's constant has a value of 6.63 times 10 to the power of negative 34 Jews per second. Units are very important times. The frequency we have above 3.55 times 10 to the power 70 hurts. We can also write one over seconds for hurts. It's the same thing before we punch in a calculator. Do our fiddler. We need to cancel out the units. And then we have to confirm that we're getting the units that we want, which is Jules for energy. And that makes sense. And now we can punch in a calculator. After that, we're going to get 2.35 times 10 to the power of negative 16 jewels for energy. Thanks for watching
