The threshold or cut-off frequency for sodium is 4,40×10 14 hz . It is subjected to radiation of frequency 9.00×10 14 hz.
What is the cutoff frequency of sodium?
The threshold or cut-off frequency for sodium is 4,40×10 14 hz . It is subjected to radiation of frequency 9.00×10 14 hz.
What is the cutoff wavelength of incident light that will produce photoelectrons from sodium?
The incident radiation has wavelength 300 nm, which is longer than the cut-off wavelength; therefore, photoelectrons are not observed. If the photoelectrode were made of sodium instead of silver, the cut-off wavelength would be 504 nm and photoelectrons would be observed.
What is your value for the cutoff frequency?
The frequency point at which the capacitive reactance and resistance are equal is known as the cutoff frequency of a low pass filter. At cutoff frequency, the output signal is attenuated to 70.7% of the input signal value or -3dB of the input. is the cutoff frequency.
What is the threshold frequency for sodium metal?
Sodium metal has a threshold frequency of 4.40×1014 Hz .
What is the maximum wavelength of sodium?
The maximum wavelength of light that can be used to eject electrons from a clean sodium metal surface is 520 nm .
How is cut off frequency calculated?
We can write the cutoff frequency equation for RC filter circuit as: f c = 1 / (2 * π * R * C ) .
What is the threshold frequency?
: the minimum frequency of radiation that will produce a photoelectric effect .
Does photocurrent depend on intensity?
A. Depends both on intensity and frequency of the incident light . Does not depend on the frequency of incident light but depends on the intensity of the incident light. ...
Does stopping potential depends on frequency?
The stopping potential does not depend on the intensity nor the number of incident photons but the stopping potential depends on the frequency of the incident light , the higher the frequency of the incident light higher the stopping potential or cut potential.
What is 3db cutoff frequency?
General Industrial Controls Pvt Ltd. 3db is the power level, its the frequency at which the power is at 3db below the maximum value and 3db means in normal unit its half the maximum power so 3db frequency means the frequency at which the power is half the maximum value so its decided the cuttoff frequency. Cite.
What happens at cutoff frequency?
In physics and electrical engineering, a cutoff frequency, corner frequency, or break frequency is a boundary in a system’s frequency response at which energy flowing through the system begins to be reduced (attenuated or reflected) rather than passing through .
What is the high pass cutoff frequency?
The cutoff frequency for a high-pass filter is that frequency at which the output (load) voltage equals 70.7% of the input (source) voltage . Above the cutoff frequency, the output voltage is greater than 70.7% of the input, and vice versa.
What is the threshold frequency or wavelength for sodium?
The threshold wavelength for sodium is 5× 10-2m .
What is Platinum threshold frequency?
The threshold frequency for photoelectric emission of electrons from platinum is 1.3 × 10^15 s^-1 .
How do you calculate threshold frequency?
It is a characteristic of electromagnetic radiation (light in case of photoelectric emission) and not metal. The formula of threshold frequency is W= hv 0 . Here v 0 is the photoelectric threshold frequency of the electromagnetic light rays, W is the work function of the metal body.
