Question

Which electromagnetic waves have the shortest wavelengths and highest frequencies?

Answer 1

The correct answer is A. Gamma Rays.  They have the shortest wave-length, and the highest frequency.  

Hope I helped.  :)

Answer 2

Answer: Gamma rays

Explanation: The given waves belong to the electromagnetic spectrum which consists of different electromagnetic radiations arranged in terms of increasing wavelengths or decreasing frequencies.

$E= h\times \nu$

$\nu=\frac{c}{\lambda}$

Thus $E=\frac{h\times c}{\lambda}$

E= energy

$\nu$= frequency

c = speed of light

$\lambda$ = wavelength

Thus frequency and wavelength are inversely related. The waves having high energies ave high frequencies and have shorter wavelengths.

Thus gamma rays having highest energy have highest frequency and shortest wavelength.
