What is it mean to refer to a matter wave? What, if anything, is “waving” and what does the matter wave tell us about a particle?

Given that the range of visible wavelengths is 380 to 760 nm, what is the range of photon energies for visible light?

Answer #1

As we know light has dual nature.

That means light waves also have particle nature.

light travels in the form of wave but interacts as a particle.


deBroglie says that when light(wave) has particle nature.

why cant particle has wave nature?

He says that nature loves symmetry. So, particle must have wave nature.

let lamda1 = 380 nm, lamda2 = 760 nm

E1 = h*c/lamda1

= 6.626*10^-34*3*10^8/(380*10^-9)

= 5.23*10^-19 J (or) 3.27 eV

E2 = h*c/lamda2

= 6.626*10^-34*3*10^8/(760*10^-9)

= 2.62*10^-19 J (or) 1.64 eV

Range of photon energies : 2.62*10^-19 J to 5.23*10^19 J

or 1.64 eV to 3.27 eV

Based on what you learned about light, select all of the correct statements from the following list. High frequency photons carry more energy than long wavelength photons. All electromagnetic waves travel at the speed of light. Light can act both as a wave and a particle. A photon is a particle of light. X-rays and gamma rays are long wavelength photons. Different types of electromagnetic radiation are fundamentally different types of waves. The only type of electromagnetic radiation that is...
