Question

Problem 23.35 (Multistep) Calculate the wave length for the following examples of sinusoidal electromagnetic radiation. (Note for comparison that an atomic diameter is about 1 × 10-10 m.) Part 1 radio, 1353 kilohertz m the tolerance is +/-2% Part 2 television, 103 megahertz m the tolerance is +/-2% Part 3 heat lamp, 4.7 × 1013 hertz m the tolerance is +/-2% Part 4 red light, 4.9 × 1014 hertz m the tolerance is +/-2% Part 5 blue light, 7.4 × 1014 hertz m the tolerance is +/-2% Part 6 x-ray, 4.1 × 1018 hertz m the tolerance is +/-2% Part 7 gamma rays, 4.5 × 1020 hertz m the tolerance is +/-2%

Answer 1

Part I frequency (0) 3 1353 x 103 HZ Sol 23.35 Part ů = 1353 kHz c= speed of the radiating signal = 3x 108 mis. As we know, the relation . . cool where, da Wavelength Where, = 3x108 1353X103 m : Hence; HE 221.73 m) Wavelogth face sendio. Hen

Part 2 forequery four television V = 103 MHz = 103 x 10' Hz - 3x 108 103 X 100 Hence, A= 2.913 m Parets for Heat lamp = 4,7 X 10'3 Hz m : 3x108 4-7x1013 Hence t = 6.38× 10-6 m Pout u foor Redelight V=4.981014 Hz ta = 3x108 m . - 4.98 1014 Hence t= 6.12 x 10-7m] 1 - - 3XL for blue light об в лом на v= 7.481014 H2 =4.05 x 10-7m do 3x102 - 7.481014 Hence. do 405x 10-7m
