- Why do astronauts use radios while talking to one another in outer space?You are working for SETI, the Search for Extraterrestrial Intelligence. One day, you receive a radio communication from an alien intelligence. Although you cannot understand their language, they have included some photos from an I Love Lucy episode. The photos allow you to determine that it is the episode in which Lucy makes a television commercial on Vitameatavegamin. This episode first aired on CBS on May 5, 1952. Before running to your supervisor to tell him the news, you quickly determine how far away in light-years the alien civilization is. (Enter the maximum possible distance.) light-years Need Help? Read It2. (a) Explain clearly why it is necessary to modulate a high frequency carrier with an information signal in order to transmit information over long distances
- A laptop computer communicates with a router wirelessly, by means of radio signals. The router is connected by cable directly to the internet. The laptop is 9.4 m from the router, and is downloading text and images from the internet at an average rate of 130 Mbps, or 130 megabits per second. (A bit, or binary digit, is the smallest unit of digital information, 1 megabit per second is 1x106 bits per second.) On average, how many bits are downloaded to the laptop in the time it takes the wireless signal to travel from the router to the laptop? Number i Units +++d-Morse code uses dots and dashes to represent symbols(letters, numbers, etc.). For example, C is -.-.and Q is --.-. How many symbols could we represent using at least one but no more than10 dots and/or dashes?A laptop computer communicates with a router wirelessly, by means of radio signals. The router is connected by cable directly to the internet. The laptop is 7.3 m from the router, and is downloading text and images from the internet at an average rate of 200 Mbps, or 200 megabits per second.

Suppose NASA transmits a microwave signal to the Space Shuttle using radio waves with a frequency of 12.GHz. Calculate the wavelength of these radio waves. Be sure your answer has the correct number of significant digits.An important news announcement is transmitted by radio waves to people who are 100 km away, sitting next to their radios, and by sound waves to people sitting across the newsroom, 3.0 m from the newscaster. Who receives the news first? Explain. Take the speed of sound in air to be 343 m/s.
