Newton's law states: The gravitational attraction force between two point masses is directly proportional to the product of their masses and inversely proportional to the square of their separation distance. The force is always attractive and acts along the line joining them. If the distribution of matter in each body is spherically symmetric, then the objects can be treate…

NettetAccording to Planck's equation, the energy of a photon is proportional to the frequency of the light, \nu ν. The amplitude of the light is then proportional to the number of photons with a given frequency. Concept check: As the wavelength of a photon increases, what happens to the photon's energy? [Show the answer] NettetAmplitude is inversely proportional to distance. Our tympanic membrane (a.k.a. our eardrum) and a microphone are both devices that measure sound intensity. When a sound arrives at our eardrum or at the diaphragm of a microphone, either of which has a certain surface area, the power in that area (i.e. the intensity) is detected. However, …
Nettet“The intensity of the light to an observer from a source is inversely proportional to the square of the distance from the observer to the source”. As per this law, light loses its brightness or luminosity as it moves away from the source. NettetThis relationship shows that fluorescence intensity is proportional to concentration. Fluorescence rarely results from absorption of UV-radiation of wavelengths shorter than 250 nm because this type of radiation is sufficiently energetic to cause deactivation of the excited state by predissociation or dissociation.
Nettet26. jan. 2024 · The intensity of light due to a slit (source of light) is directly proportional to width of the slit. The second answer posted by R C Mishra states that: The amplitude should be proportional to the width. Nettet18. okt. 2024 · A Light Sensor is a device that detects light. It generates an output signal that is proportional to the intensity of light. A light sensor measures the radiant energy present in the wide range of frequencies in the light spectrum. Some of the common frequencies are infrared, visible and ultraviolet.A Light Sensor is also called as Photo …
