The eyes of certain reptiles pass a single visual signal to the brain, where the visual receptors are struck by photons with a wavelength of 850 nm. if a total energy of 3.15 x 10⁻¹⁴ j is required to trip the signal, what is the minimum number of photons that must strike the receptor?

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
