We have a wave off given frequency 89. Find five megahertz. So we convert. Dude, I did the six fairies and we have the speed off light. Yeah, that's three. I'm stand to the eight meters per second. All right, so we just just the relationship between weight link frequency and the speed. So we get Lamb Dyke will see over F, and that gives you an answer off 3.35 meters.

People go watch frequency. It was 14 movie ruin contenders trip over three. They've bead is the post toasty between the world's 23 Indigenous to bubble, it meter for second. Waveland is a close to Linda. We have to find. Now we know that See is a cool af lender. From here we can find the video. Glenda. Them days goes t up one f which is frequency and he included in district forward it divide Brian 14 in two tenders toe problems. Sport, I need it. No one gonna need you. And some days it goes toe to 11 meter.

In this question, we tune our radios to an FM signal of 99.5. This corresponds to a radio frequency of 99.5 megahertz. We are asked what is the wavelength for this FM signal? In order to convert from a frequency to a wave link, we have to use the fundamental equation for waves. Literally. It's the speed of the wave to the wave length and frequency. Since we are asked for the wavelength, we have to solve this equation for Lambda to do this, we divide both sides by the frequency we have that lambda the way fine is equal to the speed divided by the frequency. Here C is the speed of light since we are asked about a radio wave which is a form of electromagnetic radiation. Now we just have to dio see the speed of light which is three times 10 to the eight meters per second, divided by this frequency 99.5 megahertz. To this question, we must know how to translate megahertz into exponential notation. The mega prefix is 10 to the sixth, so megahertz eagles tend to the six. Her second mega is 10 to the sixth and hurt is in units of per second for seconds in verse. Therefore, we convert this as fathers just by adding the scientific notation. Okay, so here. I mean, just clean this up here we notice the inverse seconds cancel on the top and the bottom and we will be left with units of meters, which is good since wavelength is in units of meters. Performing this division, we see that Lambda, the wavelength of this radio frequency is going to be 3.0 two, using six figs times 10 to the zero power meters. This corresponds 23.2 meters. Therefore the wavelength of this light is approximately three meters.

Hello, everyone. This is a solution to a problem. 24. Check their 24 college physics here. We're told that a radio, um uh, radio channel is broadcasting at a frequency of 600 kilohertz which here I've just converted into hurts. So this is six times in 35 Hertz and were testifying. What? Delenda or what? The Waveland off this way. This so given that the relationship between the speed of light and, um Linda F is this. So the speed of flight is equal to the weight, lead, times the frequency. We can just rearrange this for Linda to find that London is equal to see divided by F and putting in the values that we have here. We just find that this is 500 meters and that is there.
