For every cycle, the strobe light flashes two times
the frequency of strobe light is f= 6500 Hz
so that number of flashes per second is N= 6500*2= 13000 flashes/second
A strobe light is operating at a frequency of 6500 Hz. How many flashes of light...
4) If a low-pressure sodium vapor lamp emits 100 W of yellow light (frequency = 5.26 x 1014 Hz), how many photons does it emit each second? N =
A stroboscope was used to determine the frequency of the string oscillator. Strobe frequencies fs were recorded where a single stationary image of the oscillating string was observed. The frequency of the oscillator f can be determined from the stroboscope frequencies fs by f = nfs where n is an integer corresponding to the number of oscillations per flash. The strobe frequencies produced were determined and tabled below: Strobe Frequency fs Hz Oscillations per flash n 22.2 m 14.4 m+1...
Light with a frequency of 5.0x1014 Hz is incident on a diffraction grating that is immersed in water (refractive index=1.33), and the first order line occurs at an angle of 10 degrees. How many rulings (slits) does the grating have per cm? 4560 0 2900 O2180 03850 0 29000
A strobe light flash gets its energy from a 275-?F capacitor and requires 295 V to fire. If the capacitor is charged by a 325-V source through a 28-k? resistor, how long must the researcher wait between flashes? Assume the capacitor is fully discharged with each flash.
