Why a spherical sulphide screen is used in alpha ray scattering experiment?

Because it was cheap and had good fluorescence properties, meaning high light output and therefore better energy resolution.

What did the alpha scattering experiment reveal?
The alpha radiation in the experiment was detected by using a microscope and a fluorescent screen. When an alpha particle strikes the screen, the coating will fluoresce, and it will give off a "flash" of light. This small flash of light can be picked up by the investigator using the microscope.
What technology was available to Thomson that enabled him to make his discovery on atoms?
For what might be his most famous experiment, the refutation of Thomson's 'plum pudding' model, only limited apparatus was used: a source of positively charged alpha particles that would be deflected by atomic nuclei, some thin gold foil, a collimitor to narrow the beam of alpha particles, a zinc sulphide screen to register any alpha particles deflected by nuclei, and a microscope to render flashes on this screen visible to the naked eye. All in a darkened room. The various parts of the apparatus could be moved in an arc relative to one another to verify whether scattering of the alpha particles had occurred. Rutherford didn't like statistics but the results were unequivocal. Please see the link.
What equipment was use to discover the nucleus is dense and the atom is mainly empty space?
This is usually referred to as the 'gold foil' experiment. 1. You need some radiation source that releases alpha particles. This is placed inside a lead box (to block radiation) with a small pin hole to allow the escaping alpha particles to move in one direction. 2. A piece of gold foil, very thin, to be a target for the radiation. 3. A scintillation screen. (phosphorescent screen, that emit a light when struck by the alpha particles) 4. A really dark room to carry out the experiment. 5. Some kind of magnifying device to enable you to see the very weak light when an alpha particle hits the screen. 6. Some way to measure the angles of deflection of all the particles from the screen to the screen.

How does sun screen work?
sun screen works by asorbing reflecting or scattering ultraviolet light the reby reducing
Why do you have safety screen in a lab?
A safety screen, as it's name would imply, is a "screen" used for safety. it is placed between the experiment and you to provide a layer of defense from the experiment.
What equipment and technology that Ernest Rutherford use?
he used a particle emitter, gold foil and a detecting screen made from zinc sulphide

What was the purpose of the fluorescent screen in rutherfords experiment?
detect charged particles
How do you measure a strand of hair?
he diameter of a hair (or a thin string or electrical wire) can be measured by scattering laser light on the hair. The scattering creates a diffraction pattern consisting of a line of light and dark spots. If you simply measure the distance from the hair to the projection screen, and the distance from the centre to one of the dark spots, the diameter of the hair can be calculated. Ok, so you're welcome! -Livea
When an object is placed 8 millimeters from a concave spherical mirror a clear image can be projected on a screen 16 millimeters in front of the mirror. If the object has a height of 4 millimeters the?

How can you tell what colors make up white light?
The classical experiment consists in directing sunlight through a glass prism onto a screen. Light in: invisible. Light out (and displayed on screen): full spectrum of visible colors.
Is tyndall effect exhibited by the dust particles suspended in the movie projector's beam of light in a dark room?
The Tyndall effect, also called Tyndall scattering, is light scattering via particles in a fine suspension. This effect normally creates strange color tinges when only this scattered light is seen, whereas with the movie projector the only real effect of the dust is revealing the beam of light, as the light itself still hits the screen clearly.
How did Rutherford know that rays were deflecting back?
His detector screen was movable around the experiment. When he moved it to around his emitter equipment, it detected the rays, showing that some were deflecting back.
