When the frequency of light matches the natural frequency of molecules in a material light is?
When the frequency of light matches the natural frequency of molecules in a material, light is absorbed by the material. This phenomenon is known as resonance absorption.
How can one determine the threshold frequency for a given material?
The threshold frequency for a material can be determined by conducting experiments to measure the minimum frequency of light that can cause the emission of electrons from the material's surface. This frequency is unique to each material and is a key factor in understanding its photoelectric properties.
What is the frequency in photoelectric effect?
In the photoelectric effect, the frequency of incident light determines the energy of the ejected electrons from a material. Electrons are only emitted from the material when the frequency of the incident light is greater than the threshold frequency, which is unique to each material.
What happens to electrons if photon frequency is below threshold?
If the photon frequency is below the threshold frequency, the electrons do not have enough energy to be emitted from the material's surface, and no photoelectric effect occurs. The electrons will not be ejected and will remain bound to the material.
2 What happens to light when it falls upon a material that has a natural frequency equal to the frequency of the light?
When light falls on a material with a natural frequency equal to its own, resonance occurs. This causes an increase in the amplitude of the vibrations in the material, resulting in the absorption of more energy. As a result, the material may heat up or other effects may be observed, depending on the specific properties of the material.

Where does resonance occur?
Resonance can occur in any solid material where the frequency of oscillation in the material is equal to the natural frequency of the material.

How can one determine the threshold frequency for a given material or experiment?
The threshold frequency for a material or experiment can be determined by conducting a series of experiments with different frequencies of light or radiation. By gradually increasing the frequency until the material starts to emit electrons, the threshold frequency can be identified as the minimum frequency required for this emission to occur.
The frequency at which an object vibrates due to its material size or shape?
Its natural frequency.
What happens to electrons if photon frequency is below threshold?
If the photon frequency is below the threshold frequency, the electrons do not have enough energy to be emitted from the material's surface, and no photoelectric effect occurs. The electrons will not be ejected and will remain bound to the material.
How do you calculate the threshold frequency for a given material?
The threshold frequency for a material can be calculated by dividing the work function of the material by Planck's constant. The work function is the minimum amount of energy needed to release an electron from the material's surface. Planck's constant is a fundamental constant in quantum mechanics. By dividing these two values, you can determine the threshold frequency at which the material will emit electrons when exposed to light.

What is the meaning of material having sonic properties?
It means that when a particular frequency is induced into the material it will resonate.
An objects natural frequency depends partiall on the material from which it is made?
Yes, the natural frequency of an object is influenced by the material it is made from. The density and stiffness of the material play a significant role in determining how quickly the object vibrates at its natural frequency. Materials with a lower density and higher stiffness tend to have higher natural frequencies.
What is the natural frequency of a material?
The natural frequency of a material is the frequency at which it naturally tends to vibrate when subjected to a disturbance. It is determined by the material's physical properties, such as its stiffness and mass. Natural frequency is an important factor in engineering design to prevent unwanted vibrations and resonances.
