A photosensitive surface is a material or medium that reacts to light by undergoing a physical or chemical change. It is commonly used in Photography and imaging technologies to capture and record images. When exposed to light, a photosensitive surface produces a latent image that can be developed to create a visible image.
What else can I help you with?
Will brighter light eject more electrons from a photosensitive surface than dimmer light of the same frequency?
Yes, brighter light will eject more electrons from a photosensitive surface than dimmer light of the same frequency. This is because brighter light carries more energy per photon, resulting in a higher probability of ejecting electrons from the surface.
Why does violet light eject electrons from a certain photosensitive surface whereas red light has no effect on that surface?
Violet light has higher energy photons compared to red light. This higher energy allows violet light photons to transfer enough energy to electrons in the photosensitive surface to eject them, a process known as the photoelectric effect. Red light photons do not have enough energy to overcome the work function of the surface and therefore cannot eject electrons.
What effects did scientists originally think that the intensity of light shining on a photosensitive surface would have on electrons ejected from that surface?
Scientists originally thought that the intensity of light would affect the number of electrons ejected, but not their energy. They believed that increasing the intensity would only result in more electrons being emitted from the surface, without impacting their kinetic energy.
What optical device can produce a real image?
A camera is an optical device that can produce a real image. It does this by focusing light onto a photosensitive surface (like film or a digital sensor) to create a true-to-life representation of the scene being captured.
When a source of dim orange light shines on a photosensitive metal no photoelectrons are ejected from its surface What could be done to increase the likelihood of producing photoelectrons?
increase the brightness of of the orange light source
Shutter speed is associated with what?
It is associated with the length of time a photosensitive surface is exposed to light.
Will brighter light eject more electrons from a photosensitive surface than dimmer light of the same frequency?
Yes, brighter light will eject more electrons from a photosensitive surface than dimmer light of the same frequency. This is because brighter light carries more energy per photon, resulting in a higher probability of ejecting electrons from the surface.

What are some words that have photo as the root?
Photography, photosensitive, photosynthesis, photovoltaic
How do you use photosensitive in a sentence?
The old painting is photosensitive to light.
What is photosensitive device?
Reacts to light.
What is a Photosensitive drum?
Aluminum cylinder coated with particles of photosensitive compounds. Used in a laser printer and often contained within the toner cartridge.

Where can you get photosensitive paper?
Rowe Photo, Walgreens
What is the definition of photosensitive?
Something that is affected by light.
What is the effect of light on photosensitive film?
Too much light on photosensitive film can cause the picture to immediately corrode. This is why many photographers use a darkroom.
What are photosensitive epileptic seizures?
Seizures for people who have photosensitive epilepsy. They are caused by reactions to light, like flashing lights, strobe lights, flickering lights etc.
