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.
How could an alpha particle strike the phosphor screen on the same side of the foil as the alpha particle source?
An alpha particle could strike the phosphor screen on the same side of the foil as the alpha particle source if it undergoes a scattering event with a nucleus that causes it to change direction and travel back towards the same side. This scattering event can happen due to the strong Coulomb interaction between the positive charge of the alpha particle and the positive charge of the nucleus.
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.
In young's double slit experiment two slits are made 1mm apart and the screen is placed 1m awaywhat is the fringe separation when blue light of 500cm is used?
The fringe separation can be calculated using the formula: fringe separation = wavelength * distance to screen / distance between slits. For blue light with a wavelength of 500 nm and a distance of 1m to the screen and 1mm between the slits (1mm = 0.1 cm), the fringe separation comes out to be 0.05 mm or 50 micrometers.

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 is the distance from the slits to the screen in the double-slit experiment?
In the double-slit experiment, the distance from the slits to the screen is typically several meters.
What equipment and technology that Ernest Rutherford use?
he used a particle emitter, gold foil and a detecting screen made from zinc sulphide

What are the different types of CRT monitors?
1.spherical,2.cylindrical,3.standard,4.short neck,5.flat screen.
How did young achieve the condition of phase coherence in young double slit experiment?
The condition of phase coherence in the Young double-slit experiment is achieved by using a monochromatic light source, which emits a single wavelength of light. This means that all the light waves interfering with each other have the same frequency and are in phase with each other. This results in the characteristic interference pattern observed on the screen.
What was the purpose of the fluorescent screen in rutherfords experiment?
The purpose of the fluorescent screen in Rutherford's experiment was to detect the alpha particles that were deflected when they struck the gold foil. The screen would light up when hit by the alpha particles, allowing Rutherford to observe and measure the deflection pattern and infer the structure of the atom.
How many bright fringes can be observed on a screen in a double-slit interference experiment?
In a double-slit interference experiment, the number of bright fringes observed on a screen is determined by the formula: n (dsin)/, where n is the number of bright fringes, d is the distance between the slits, is the angle of the bright fringe, and is the wavelength of the light.
How could an alpha particle strike the phosphor screen on the same side of the foil as the alpha particle source?
An alpha particle could strike the phosphor screen on the same side of the foil as the alpha particle source if it undergoes a scattering event with a nucleus that causes it to change direction and travel back towards the same side. This scattering event can happen due to the strong Coulomb interaction between the positive charge of the alpha particle and the positive charge of the nucleus.
