Bose became interested in radio following the 1894 publication of British physicist Oliver Lodge 's demonstrations on how to transmit and detect radio waves. He began his own research in the new field in November 1894, setting up his equipment in small 20 ft sq room at Presidency College. Wanting to study the light-like properties of radio waves which were hard to study using long radio waves, he managed to reduce the waves to the millimetre level (in the microwave range of about 5 mm wavelength).
