Which scientist first discovered that white light is a mixture of a rainbow spectrum of light rays?
Isaac Newton was the scientist who first discovered that white light is a mixture of a rainbow spectrum of light rays through his experiments with prisms in the 17th century.
Who discovered that light travels in straight line?
Ibn al-Haytham (965 in Basra - c. 1040 in Cairo) a Muslim scientist, proved that rays of light travel in straight lines, and carried out various experiments with lenses, mirrors,refraction, and reflection. He was also the first to reduce reflected and refracted light rays into vertical and horizontal components, which was a fundamental development in geometric optics.Book of Optics.(Ibn al-Haytham)
What did experiments with cathode rays lead to the discovery of what?
experiments with cathode rays lead to the discovery of the Electron.
What was the scientist name who discovered the electrons charge?
The scientist who discovered the charge of electrons was J.J. Thomson. He determined the charge-to-mass ratio of electrons through his experiments with cathode rays in the late 19th century.
Experiments on cathods rays describe the experiments that showed that cathods rays are negative particles?

Named the scientist who coined the term 'electron'?
The scientist who coined the term "electron" was J.J. Thomson. He discovered the electron in 1897 while working on experiments involving cathode rays.
What can scientist measure when light rays are emmitted by a moving source?
When light rays are emitted by a moving source, scientists can measure the Doppler effect, which is the change in frequency or wavelength of a wave in relation to an observer moving relative to the source. By analyzing the Doppler effect, scientists can determine the velocity and direction of the moving source.
How j.j Thomson discovered electrons are negative?
J.J. Thomson discovered electrons are negative by conducting experiments with cathode rays in vacuum tubes. He observed how the rays were attracted to a positively charged plate, leading him to conclude that the particles in the rays carried a negative charge, which he named electrons.
Did J J Thomson's experiments with cathode rays lead to the discovery of the neutron?
No. JJ Thomson's experiments with cathode rays lead to the discovery of the electron.
What is the transfer of energy carried in rays?
Energy transfer in the form of rays typically refers to electromagnetic radiation, such as light. This transfer occurs when energy is carried by waves moving through space, without the need for a medium. Examples include sunlight transferring energy to Earth and X-rays in medical imaging.
What was the name of the scientist who was credited with the discovery of the cathode ray?
The scientist credited with the discovery of the cathode ray is J.J. Thomson. Thomson conducted experiments with cathode rays in the late 19th century and discovered the electron, which revolutionized our understanding of atomic structure.
What was Thompson working with when he discovered the cathode rays?
Thomson discovered cathode rays when he was working with electrons. He was performing experiments with the electrons when one of them became electrically charged and a beam of light came from it, this creating a cathode ray.
