1.	Which of the following waves have short wave-length?(a) Microwave(b) Radio wave(c) Gamma rays(d) IR wavesThe question was posed to me by my school teacher while I was bunking the class.The doubt is from Monitoring Labour Activity in section Foetal Monitoring Instruments of Biomedical Instrumentation
Answer» The correct choice is (C) GAMMA rays The best I can EXPLAIN: Electromagnetic spectrum ranges from very short WAVELENGTHS (including gamma and X-rays) to very LONG wavelengths (including microwaves and broadcast radio waves). The range of wavelength of gamma rays and X-rays is 10^-4 to 10 nm. The range of wavelengths of microwaves and radio-waves is 10^6 to 10^9 nm.
