Explanation Given: The distance from earth to sun is 1.5 × 10 8 k m Frequency of light is 1 .0×10 14 s − 1 Wavelength: Wavelength of any wave is the distance between consecutive peaks or troughs. It is denoted by λ. The unit of wavelength is m, cm, nm, mm etc. Frequency: Frequency of any wave is the number of oscillations per second or the number of oscillation in one second. It is denoted by v. The unit of frequency is per second. Its SI unit is Hz, which is equal to s -1 . Formula used: c = λ ν v = c λ λ = c v where, v = frequency, λ = Wavelength and c= Velocity or speed Calculation: Now calculate the wave length of light: λ = c v = 3.0 × 10 8 m / s 1 ...

Hi, I need help on my practice final, If you could offer strategies and dumb it down for me with an explanation on how to solve that would be amazing and beneficial.

Hi I need help with my practice final, it would be really helpful to offer strategies on how to solve it, dumb it down, and a detailed explanation on how to approach future similar problems like this. The devil is in the details and this would be extremely helpful

In alpha-NbI4, Nb4+ should have the d1 configuration (bond with paired electrons: paramagnetic). Please comment.
