What is a semiconductor device that produce electric current through the photo-voltaic is an?
A semiconductor device that produces electric current through the photo-voltaic effect is a solar cell. When sunlight shines on the cell, it creates an electric current by releasing electrons from the material. This electric current can then be harnessed for various applications, such as generating electricity for homes or powering electronic devices.
What device is known when electrons are emitted when light shines on a metal surface?
The device you are referring to is a photoelectric cell or a photodiode. When light shines on the metal surface of these devices, electrons are emitted in a process called the photoelectric effect, which generates an electric current.
What is a device that spins when the sun shines on it?
radiometer
What is the shine of tungsten?
Tungsten has a high shine and luster, with a metallic appearance. It is known for its resistance to tarnishing and its ability to maintain its shine over time.
What are lumos in Harry Potter game?
Creates light, that shines from the tip of the wand.
What are solar cells made of and how do they work?
Solar cells are typically made of silicon, a semiconductor material. When sunlight shines on the solar cell, it creates an electric field across the layers of silicon, causing electrons to flow, generating an electric current. This current is captured and converted to usable electricity for powering devices or homes.
Where can one purchase a '200mw laser'?
A 200mw laser is a device that shines a laser beam. These can be bought from Amazon, eBay as well as stores specializing in this type of device, such as Lazerpoint.
What device makes electrons emit when light energy shines on a metal surface?
You think probable to an ultraviolet lamp.
What happens to the silicon layers in a solar cell when the sun shines on it?
When sunlight shines on the silicon layers in a solar cell, the photons in the sunlight excite the electrons in the silicon, causing them to move and create an electric current. This process generates electricity, which can then be used to power various devices.
What device converts electromagnetic radition into heat energy?
Heat Lamp. Is a lamp that shines heat energy ( electromagnetic Energy) into the form of heat.
Is it true in he phenomenon known as the photoelectric effect electric current will flow when light shines on certain substances?
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.
What happens to the spectrum if a red light shines on a prism?
When red light shines on a prism, it will refract and disperse into its component colors (red, orange, yellow, green, blue, indigo, violet) due to their different wavelengths. This creates a spectrum of colors known as a rainbow.
