Will the photoelectric effect change for different targets

Yes, the photoelectric effect can change for different targets. The photoelectric effect refers to the emission of electrons from a material surface when it is illuminated by light or other electromagnetic radiation. The effect depends on various factors, including the properties of the target material.

One of the key factors is the work function of the material. The work function is the amount of energy required to remove an electron from the material's surface. Different materials have different work functions, which can vary greatly. So, when light of a specific frequency or energy (related to the wavelength) is incident on a target material, electrons will be emitted only if the energy of the light is greater than or equal to the work function of the material.

Another factor is the binding energy of the electrons within the material. In different materials, the electrons are bound to the atoms with different strengths. This affects the ease with which the electrons can be released from the material's surface when illuminated.

Additionally, the number of available electrons and their mobility within the material can also impact the photoelectric effect. Some materials may have a more abundant supply of free electrons compared to others, or the electrons may be more easily liberated.

To determine how the photoelectric effect will change for different targets, you need to consider the properties mentioned above: work function, binding energy, and the availability and mobility of electrons within the material. Experimental measurements or theoretical calculations specific to the target material will be necessary to obtain accurate information about how the photoelectric effect may vary.
