In a vacuum, electromagnetic radiation of short wavelengths a. travels as fast as radiation of long wavelengths. b. travels slower than radiation of long wavelengths. c. travels faster than radiation of long wavelengths. d. can travel both faster and slower than radiation of long wavelengths.

In a vacuum, electromagnetic radiation of short wavelengths travels as fast as radiation of long wavelengths. Correct A

There is no difference in the speed of the electromagnetc waves with different wavelengths. The speed does not depend of the wavelenght of the wave. Or in other words, a change in the frequency (or wavelength) of a wave does not affect the speed of the wave .

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.

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".
