Answer:
true
Explanation:
i took the quiz :) so i hope this helps
De Broglie's equation is used to show that photons have both particle and wave nature. photons are quantized packets of energy. the wave nature of photons can be proven as they have a wavelength. the particle nature is given by them having both velocity and mass.
de Broglies equation is;
λ = h / p
where λ - wavelength
h - Planck's constant
p - momentum
substituting the values in the equation
p = h/λ

p = 2.20 x 10⁻²⁷ kgm/s
momentum of photon is 2.20 x 10⁻²⁷ kgm/s

This question is hard :( I dont know im so sorry
Explanation:
As against non-metals are the elements which are usually soft. ... Generally, the elements containing 1,2 or 3 electrons in the valence shell of their structure are known as metals. While the elements with 4, 5, 6 or 7 electrons in their outermost shell are known as non-metals.
