Question

question 4
which kind of rays on the electromagnetic spectrum has the shortest wavelength and highest energy?
select one:
a. gamma rays
b. infrared waves
c. microwaves
d. radio waves

Explanation:

Gamma rays have the shortest wavelength and highest energy in the electromagnetic spectrum. This is based on the properties of electromagnetic waves where shorter wavelengths correspond to higher frequencies and thus higher energy (using the relationship \(E = h
u=\frac{hc}{\lambda}\), where \(E\) is energy, \(h\) is Planck's constant, \(
u\) is frequency, \(c\) is the speed of light, and \(\lambda\) is wavelength). Among the options: radio waves (\(D\)) have long wavelengths and low energy; microwaves (\(C\)) have longer wavelengths than infrared (\(B\)) and gamma rays (\(A\)); infrared waves (\(B\)) have longer wavelengths than gamma rays.

Answer:

A. Gamma rays
