Indicate the correct arrangement for electromagnetic radiation in order of their increasing wavelength.
Answer : Option B
Explanation : The Electromagnetic spectrum in order of decreasing energy, thus increasing wavelength : Gamma Rays–wavelength: 0.01 nm ; X-rays –1 nm ; Ultra-violet Rays-0.1 micrometres ; Visible Light- Red light : 0.7 micrometres, Violet Light : 0.4 micrometres ; Infrared Radiation–0.01 mm ; Microwaves -less than 10 cm, usually 1cm ; Radiowaves- Long, Medium and Short Waves : 2 km-10 m ; and Very High Frequency (VHF) and Ultra High Frequency (UHF): 10 m–10 cm.
