A cathode ray is a stream of electrons, not a stream of photons like the electromagnetic wave. It's a different type of particle. The electrons don't move at light speed in a vacuum; also, they are electrically charged.

∙ 13y agoA cathode ray is a stream of electrons. Electromagnetic waves are beams of photons. Different forms of matter/energy, with totally different properties. The cathode ray is made by ionizing a cathode, releasing it's electrons in a stream. Photons are exchanged between atoms constantly, at a rate of many billions of times per second.

What following piece of equipment was used by jj Thomson to find electrons?
JJ Thomson discovered electrons using a cathode ray tube.
A cathode ray is deflected away from a negatively charged object What property of the cathode ray is shown by these phenomena?
The property shown by the phenomena is that the cathode ray is negatively charged. A cathode ray is also called an electron beam or an a-beam.
Which has the lowest frequency in the electromagnetic spectrum microwaves radio waves visible light or gamma rays?
Radio waves have the lowest frequency in all of the electromagnetic spectrum. The next higher frequency energy is microwave, visible light including ultraviolet, infrared, X-ray, then gamma ray
Which ray is the fastest gamma alpha beta?
Gamma rays. Since they are electromagnetic waves, they travel at the speed of light.
What is the reason for ultrasonic waves not being in the form of electromagnetic waves?
Ultrasonic waves are high frequency sonic waves. They're sound, which is mechanical energy. Electromagnetic waves are waves of electromagnetic energy, like radio waves or light. Mechanical energy is different from electromagnetic energy, hence the reason for ultrasonic waves not taking the form of electromagnetic waves.
How are an infrared ray and gamma ray similar?
Both are electromagnetic waves (electromagnetic radiation or electromagnetic energy).
X-ray longitudinal or transverse?
X-rays are a type of electromagnetic waves; electromagnetic waves are transverse waves.
What are the electromagnetic waves from smallest wavelength to largest?
With longest wavelength to shortest Radio waves, micro waves, infra red, visible radiations, ultra violet, X-ray and Gamma ray
Are cathode rays electromagnetic waves?
Cathode rays are not electromagnetic rays because the cathode ray is a beam of electrons that travel from the negatively charged to positively charged end of a vacuum tube, across a voltage difference between the electrodes placed at each end.The electrode at the negative end is called a cathode; the electrode at the positive end is called an anode.Since electrons are repelled by the negative charge, the cathode is seen as the "source" of the cathode ray in the vacuum chamber.
Which of the electromagnetic waves do you use for medical purposes?
radioIRX-Ray
Is a radio wave a gamma ray?
No. Though both are electromagnetic waves.
What following piece of equipment was used by jj Thomson to find electrons?
JJ Thomson discovered electrons using a cathode ray tube.
Is a gamma ray an example of a mechanical wave?
No. A gamma ray is a very high frequency electromagnetic wave. Electromagnetic waves propagate as a combination of changing electric field and changing magnetic field. Electromagnetic waves can travel through empty space without any medium. Mechanical waves (such as sound and water waves) propagate by the oscillating particles of the medium - they require a medium to move through.
What kind of wave is an x ray?
X-Rays are part of the electromagnetic spectrum. Other waves on the electromagnetic spectrum include light, radio waves, and gamma rays.
Do X-ray waves need a medium?
No. X-rays are a form of electromagnetic wave. Electromagnetic waves self-propagate by generating their own electrical and magnetic fields.
Why is a sonogram a safer way to view a developing fetus than an X-ray?
Because the strength of the electromagnetic waves from a sonogram are significantly less than the strength of the electromagnetic waves from an X-ray machine, therefore: the waves have less of an impact on the developing cells of the fetus.
Ray of radiation traveling from the cathode to the anode?
Cathode Ray
