Answer:

462nm

Explanation:

E=hf

c=fλ

E=hc/λ

The relation between the wavelength λ of a photon and its energy E is following: E=hc/λ where h = 6.626×10⁻³⁴ J⋅s is Planck’s constant, c = 3×10⁸ m/s is the speed of light. If E = 4.56×10^⁻¹⁹ J then λ = 463nm(nano meter)

Define diffusion. Is it faster in summer or winter season?
Basile [38]
Diffusion is the process of a substance spreading out to evenly fill its container or environment. Kinetic energy of particles of matter increases with an increase in temperature. More the kinetic energy in the particles, more is the rate of diffusion. so diffusion is faster in the summer!

hope this helps!
