1. WBIM-FM is the Bridgewater college radio station. It broadcasts at a frequency of 91.5 MHz (MHz = megahertz = one million Hertz = 1,000,000 cycles per second = 10⁶ Hz). What is the wavelength of this radio wave? Compare its size to something you are familiar with (object you own, yourself, your car, a city block, etc. be original)

2. During what season will more insolation be delivered to a vertical south-facing window on a clear day? During what season will more insolation be delivered to a horizontal skylight on the roof of the same house?

3. The insolation reaching a surface is made up of three components of solar radiation. Name and describe these components.

4. Explain in your own words the difference between renewable and nonrenewable energy resources. Is nuclear energy a renewable or nonrenewable resource?

5. List five renewable energy resources consumed in the United States. List them in order from most to least used.

6. Sunlight is especially intense in the visible light region of the electromagnetic spectrum. Yellow light has a frequency of 525 THz (terahertz, 1 THz = 10¹² Hz). What is the wavelength of a wave of yellow light. Compare its size to your answer for the radio wave in question # 1 above.

Expert Solution

These are electromagnetic waves: radio, microwave, infrared, visible light, ultraviolet, x rays, gamma rays. And all of these have the same velocity, light velocity. There's a relation between frecuency, wavelenght and velocity of the wave:

, in this case v is the light velocity and it's reasonable to assume the value in the vacuum:

Insolation is the total amount of solar radiation energy received on a given surface area during a given time. For this we need to have the sun perpendicular to that area. The sun changes its place on the sky due to our rotation around him, this results in seasons: winter, summer, spring, autumn. In summertimes the sun is higher compared to the other seasons. During winter is lower. So know think when the insolation will be greater on a vertical surface and on a horizontal surface.

Components of solar radiation: infrared, ultraviolet and visible light. You can look these up on internet easily.

4 and 5 should be answered by you after doing a little research on books or internet, it will be interesting learning about that.

6 is like the first one, all you have to change is the value of frecuency which now is 525 x10¹² Hz and that's it.

Those are pretty good questions and all of us should have notion of this subject. Good luck!

Public Radio station KXPR-FM in Sacramento broadcasts at 88.9 MHz. The radio waves pass between two tall skyscrapers that are 15.0 m apart along their closest walls. 1) At what horizontal angles, relative to the original direction of the waves, will a distant antenna not receive any signal from this station? 2) If the maximum intensity is 4.00 W/m2 at the antenna, what is the intensity at ±4.00∘ from the center of the central maximum at the distant antenna? I=...

You've decided to build a radio to listen to your favourite FM radio station, which broadcasts at 102.9 MHz. For the tuner, you'll be using an RLC circuit, but the only inductor you happen to have on hand has a value of 0.870 μH. Unfortunately, there's another radio station — which you don't want to listen to — at a nearby frequency of 103.3 MHz. To prevent any interference from this 103.3 MHz radio station, you want the peak current...

FM Radio Interference

You are listening to the FM radio in your car. As you come to a stop at a traffic light, you notice that the radio signal is fuzzy. By pulling up a short distance, you can make the reception clear again. In this problem, we work through a simple model of what is happening.Our model is that the radio waves are taking two paths to your radio antenna:the direct route from the transmitteran indirect route via reflection off a buildingBecause...
