The modern quantum model of the atom says that electrons behave like light in being these two at the same time
What are particle and the wave?
200
What does light need to travel?
What is nothing?
200
Which one has more energy UV rays or Infra Red and therefore are more harmful?
What is UV rays?
200
The electrons need this to jump from one energy level to higher energy level
What is a photon or a quanta of energy?
200
Who discovered the relationship between energy and matter in his famous equation E=mc2
What is Einstein?
200
Photoelectric effect is the process of shooting off this using light
What is electron?
300
What kind of radiation is light?
What is electromagnetic?
300
If a wave has bigger wavelength, then it will have this frequency?
What is lower?
300
The electrons behave both like this two things
What is a particle and a wave?
300
Who stated that the position and the speed of the electrons cannot be determined simultanously?
What is Heisenberg?
300
The flow of this is called electricity
What is electron?
400
What is the name of the radiation that has lowest wavelength and highest frequency and is very powerful?
What is gamma rays?
400
One of the most dangerous waves is gamma rays as they have low wavelength, therefore high frequency and high this and it can penetrate through everything.
What is energy?
400
This the name of the state where the electron exists before being moved to a higher energy level
What is ground state?
400
Who did the famous thought experiment to prove that electrons position cannot be determined without us observing it. (Hint: Meow)
Who is Schrodinger?
400
The movement of electrons from excited stage back to the ground state emits this.
What is light?
500
The particle of light is called this
What is a photon?
500
What is the distance between two crests of a wave called?
What is wavelength?
500
The color of light depends on this two things
What is the level of energy that the electron falls from and to?
500
Who discovered the relationship between energy and frequency. E=hv
