(n) which one of the following statensthe same s the sane resistors in series is true? (a) the voltage across each resistor e current through cach resistor is the same (c) the total current through the currents through each resistor (d) the p resistor the combination of resistors is the sum of the dissipated by each resistor is the same. (o) when a ray of light meets an optically the reflected ray is determined by: the direction taken by meets an optically flat reflecting surface (a) the material of the reflecting surface. (b) the angle of incidence (c) the intensity of the light. (d) the refractive index of the medium. the second maxmme i at the slits and travel to a distant screen to produce by the waves is: of the interference pattern. the diter nterference pattern. the difference in the distance travelled (a) half a wavelength. (b) three halves of a wavelength. (c) a quarter of a wavelength. (d) two wavelengths. -rays produced with a copper anode are often used in x-ray diffraction for determining molecular structures since: (a) these x-rays are highly penetrating. (b) these x-rays have extremely large wavelengths c) these x-rays have wavelengths comparable to inter-atomic spacings in chemical and biological molecules. (d) copper anodes are inexpensive. r esoffece hetween two waves that give rise to a dark spot in young's double-slit experiment might be: (a) zero. (b) π/4 radians. (c) 2t radians. (d) π radians. (s) when you stand in front of a plane mirror, your image is: (a) real, erect and smaller than you. (b) real, erect and the same size as you. (c) virtual, erect and smaller than you. (d) virtual, erect and the same size as you.
