If you used the doppler effect as a reason not to get a ticket for running a red light in the situation in no. 1, how much of a fine would you get for speeding? Assume that the fine is P50.00 for each kph (km per hour) that your speed exceeds the posted limit of 95 kph.
(a) How fast must you be approaching a red traffic light (λ=700 nm) for it to appear yellow ( λ=575)?
A ray of light is incidented at angle 60° in air on air glass plane surface.find the angle of refraction of the glass (aΠg =1•5) in calculation method
physics teacher has demonstrated a single slit diffraction experiment to the students with a light source of wavelength 400 nm and grating constant of 4000 lines per inch. Compute maximum number of dark fringes observed by him?
a marble rolls off the of a table top with an initial speed of 15.0 m/s. it strikes the floor 2.0 from the base of the table. (a) How long ( t = ? ) does it take the marble to reach the floor, what is the height of the table.
