Can the human eye detect gamma rays?
No, this is why the rescue crews at Chernobyl died so horribly; they didn't notice the sheer amount of radiation in the air around them., From an evolutionary point of view, there is no reason why human beings should be able to sense gamma rays.
How radiation was discovered?
In 1896 Henri Becquerel was using naturally fluorescent minerals to study the properties of x-rays, which had been discovered in 1895 by Wilhelm Roentgen. He exposed potassium uranyl sulfate to sunlight and then placed it on photographic plates wrapped in black paper, believing that the uranium absorbed the sun's energy and then emitted it as x-rays. This hypothesis was disproved on the 26th-27th of February, when his experiment "failed" because it was overcast in Paris. For some reason, Becquerel decided to develop his photographic plates anyway. To his surprise, the images were strong and clear, proving that the uranium emitted radiation without an external source of energy such as the sun. Becquerel had discovered radioactivity. Becquerel showed that the radiation he discovered could not be x-rays. X-rays are neutral and cannot be bent in a magnetic field. The new radiation was bent by the magnetic field so that the radiation must be charged and different than x-rays. When different radioactive substances were put in the magnetic field, they deflected in different directions or not at all, showing that there were three classes of radioactivity: negative, positive, and electrically neutral So basically radiation was discovered by accident
What is used to make photographic film?
Photographic film was invented in 1889 by George Eastman. Photographic film and paper is made using silver nitrate which is light sensitive.
What year was Pluto discovered?
Pluto was discovered in 1930 by Clyde Tombaugh.
What is photographic communication?
using these photographs to convey an idea or information

Colloid can be detected by using?
deffinatly Mohs
What are safety precautions for using infrared radiation?
There are many different kinds of radiation and the appropriate safety precautions are different for the different kinds. The precautions for using microwave radiation, for example are very different from the precautions for using gamma radiation, or infra red radiation.
Which types of electromagnetic radiation can be detected using telescopes on Earth?
They can detect radio waves, infrared radiation, ultraviolet radiation, x-rays, and gamma rays.
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 is a good sentence for plates?
I saw a man juggling six plates! We are using paper plates this evening.
What is an early photographic process using silver plate developed in mercury vapour?
Daguerreotype
