Find energy is the wavelength is 5.2x10^-7m (Show work)

E = 3.825×10⁻¹⁹ J

Explanation:

Wavelength of photon = 5.2 ×10⁻⁷m

Energy of photon = ?

Solution:

Formula:

E = hc/λ

h = plancks constant = 6.63×10⁻³⁴ Js

c = speed of wave = 3×10⁸ m/s

by putting values,

E = 6.63×10⁻³⁴ Js ×3×10⁸ m/s / 5.2 ×10⁻⁷m

E = 19.89×10⁻²⁶ J.m / 5.2 ×10⁻⁷m

E = 3.825×10⁻¹⁹ J

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
