Question

22) — 22) Using the figure below, categorize electromagnetic radiation with a wavelength of 1.0 x 10-3 m. Wavelength 10-3 10-1 10 103 105 107 109 1011 1013 (nm) Frequency 1020 1018 1016 1014 1012 1010 108 106 104 X rays Ultra- viloet Visible Infrared Microwave Radio waves Gamma Type of rays radiation A) X rays B) Ultraviolet C) Infrared D) Gamma rays E) Microwave

Answer 1

In the figure Wave length given in nanometer scale hence 1013 Am = (1013x10-9hm. = 104 m 101 nm = (10 13 x 10-9) m = 10² m. 103 nm - ( 109 x 10-9 ) m-olm 107 nm- (107 x 10-9 ) m = 10-2 105 um ² (105 x 10-om = 10-4 m 107 to 105 is range of micro- wave. 1x10-3 lies in the between 107 nm to 105 nm, which is micro- wave range. E) is correct ans.
