It is not true that the Doppler effect has anything to do with electricity and the flow of current. The Doppler effect involves pitch and sound frequency of moving objects, for example the apparent noise changes of an approaching car.
Yes, in the photoelectric effect, electric current is produced when light shines on certain substances known as photosensitive materials. This occurs when photons (particles of light) strike the material's surface and transfer their energy to electrons, causing them to be ejected and generate an electric current.
The Doppler Effect is the change in the frequency of the sound you hear when a car sounding its horn passes you.When the electrons at the surface of an object absorb incident light sufficient for them to escape the surface this is known as the photoelectric effect.
Piezoelectric substances are materials that generate an electric charge when mechanical stress is applied to them. This property allows them to convert mechanical energy into electrical energy and vice versa. Common examples of piezoelectric substances include quartz, ceramics, and certain crystals.
The glow seen under ultraviolet light is called fluorescence. This phenomenon occurs when certain substances absorb ultraviolet light and then emit visible light in response.
Piezoelectricity is the ability of certain materials to generate an electric charge in response to mechanical stress, such as squeezing or pressing. This phenomenon occurs because the crystal structure of piezoelectric materials can produce electric polarization when subjected to mechanical deformation, leading to the generation of an electric field.

basically metals get charged by getting extra electrons or by missing them. baut certain substances get there charges by a physical phenomenon ,like friction ,heating,or any chemical reactions , it all results in electron transfers, and the substance get charged.
The phenomenon whereby the refractive index of certain substances varies with light intensity
Yes, in the photoelectric effect, when light shines on certain substances, electrons are ejected from the material, creating an electric current. This effect occurs when photons (light particles) transfer enough energy to electrons in the material to overcome the binding energy holding them in place.

The phenomenon that you are not certain
Substances that conduct an electric current under certain conditions are most likely to be metals or solutions containing ions. Metals have free electrons that can move through the material, allowing for the flow of electric current. Ionic solutions contain ions that can move and carry charge, enabling them to conduct electricity.
