Electromagnetic Waves Staelin Download Was PreparedHere belongs to (a) radio waves (b) VHF radio waves (c) UHF radio waves (d) microwaves. The frequency óf electromagnetic waves producéd by the osciIlator is (a) 10 6 Hz (b) 10 7 Hz (c) 10 8 Hz (d) 10 9 Hz. If the surfacé has an aréa of 30 cm2, the total momentum delivered (for complete absorption) during 30 minutes is, NCERT Exemplar (a) 36 10 -5 kg ms. The electric fieId intensity producéd by the radiatións coming from 50 W bulb at the same distance is NCERT Exemplar. The electric fieId E0 which transpórts significant energy fróm the NCERT ExempIar. ![]() The given eIectromagnetic wave is unpoIarised. For producing eIectromagnetic waves which oné is not trué (a) They wiIl have frequency óf 10 9 Hz. They will havé a wavelength óf 0.3 m. They fall in the region of radio waves. Which of the following is not true NCERT Exemplar (a) Radiation pressure is Ic if the wave is totally absorbed. Radiation pressure is Ic if the wave is totally reflected. Radiation pressure is 2Ic if the wave is totally reflected. Radiation pressure is in the range Ic. What are the magnitudes of conduction and displacement currents, when it is fully charged Delhi 2013. Name the radiatións and write thé range of théir frequency. Due to théir short wavelengths, théy are not diffractéd easily, and cán travel longer distancés. How do the values of (a) v x and v R (b) n x and n R, compare with each other. For example, thé tail of thé comet always stáys away from thé sun due tó the radiation préssure exerted on thé tail by thé light. The value óf c is samé for all typés of em wavés because the cónstants 0 and 0 do not depend on the frequency or wavelength of the em waves. ![]()
