In the equation Enhf, energy (E) is directly proportional to the frequency (f) of a photon. Planck's constant (h) is a constant that relates the energy of a photon to its frequency. The variable n represents the number of photons.
The energy of electromagnetic radiation is directly proportional to its frequency. This relationship is described by Planck's equation: E = hν, where E is the energy, h is Planck's constant, and ν is the frequency. This means that as the frequency of electromagnetic radiation increases, so does its energy.
The value of Planck's constant is approximately 6.626 x 10^-34 m^2 kg / s. It is a fundamental physical constant that relates the energy of a photon to its frequency.
The energy of a photon can be calculated using the formula E = h*f, where E is energy, h is Planck's constant (6.626 x 10^-34 J.s), and f is frequency. Plugging in the values, the energy of a photon with a frequency of 4.1 x 10^7 Hz would be approximately 2.72 x 10^-26 Joules.
The maximum kinetic energy of the emitted photoelectron can be calculated using the equation: KE = hf - work function = hc/λ - work function . Substitute the given values, where h is Planck's constant, f is frequency, c is the speed of light, and λ is the wavelength. Find the maximum kinetic energy by calculating the difference between the energy of the incident light and the work function.
Wave speed, frequency, and wavelength are independent of wave amplitude. Wave speed is determined by the medium through which the wave is traveling, frequency is the number of oscillations per unit time, and wavelength is the distance between two consecutive points in phase. Amplitude, on the other hand, is the maximum displacement of a wave from its equilibrium position.

wavelength since frequency =hc/lambda h=plancks constant and c=velocity of light

I assume the equation you're looking for is E=hv or E=hc/lambda. h is plancks constant and c is speed of light in m/s. lambda is in metres
LEDs (Light Emitting Diodes) are used in determining the Planck constant because they emit light at specific frequencies when electrical current is applied. By measuring the voltage needed to produce light of a known frequency, the relationship between energy and frequency can be studied, allowing for the accurate determination of the Planck constant.
The value of Planck's constant is approximately 6.626 x 10^-34 m^2 kg / s. It is a fundamental physical constant that relates the energy of a photon to its frequency.
Planck's constant relates the energy level of radiation due to electrons moving from one energy level to another, by the formula Energy = (Planck's constant) x (frequency of radiation). Therefore the dimensions of Planck's constant are (energy)/(frequency) which means Joules x seconds In fact Planck's constant = 6.67 x 10-34 joule.seconds.
No, gas constant is having a value of 8.314Jk-1mol-1 Whereas plancks constant has a value of 6.6*10-31

to find the frequency of a light wave you need to know its wavelength. The frequency is equal to the speed of light (3x10^8 m/s) divided by the wavelength in metres. Alternatively, if you were given the energy of each photon of light in joules you could just divide the energy by plancks constant (6.63x10^-34) to leave you with the frequency in Hz.
Planck's constant is a fundamental constant in physics that relates the energy of a photon to its frequency. It is denoted by the symbol ( h ) and has a value of approximately ( 6.626 \times 10^{-34} ) joule-seconds. This constant is crucial in quantum mechanics, as it helps explain how energy is quantized at the atomic and subatomic levels. Essentially, it shows that energy comes in discrete packets, or "quanta."
The maximum kinetic energy of the emitted photoelectron can be calculated using the equation: KE = hf - work function = hc/λ - work function . Substitute the given values, where h is Planck's constant, f is frequency, c is the speed of light, and λ is the wavelength.
