Which of the following has the high energy
Correct answer: D. Gamma rays
- A. Visible light
- B. X rays
- C. Ultraviolet rays
- D. Gamma rays
Explanation
Reasoning:Energy of electromagnetic waves is directly proportional to their frequency and inversely proportional to their wavelength. This relationship can be expressed using the following equation:E = h * vwhere:E is the energy of the waveh is Planck's constant (a fundamental physical constant)v is the frequency of the waveTherefore, higher frequency corresponds to higher energy.Among the options given, gamma rays have the highest frequency and therefore the highest energy. Here's a brief comparison of the options:Visible light: This range encompasses a spectrum of colors with varying frequencies and energies. It falls within the lower end of the electromagnetic spectrum.Ultraviolet rays: These rays have higher frequencies and energies than visible light, but they are still less energetic than X-rays and gamma rays.X-rays: These possess even higher frequencies and energies compared to ultraviolet rays.Gamma rays: These have the highest frequencies and highest energies among the listed options. They are a form of ionizing radiation, meaning they have enough energy to knock electrons out of atoms.Therefore, gamma rays is the correct answer as it has the highest energy compared to the other options.

About Electromagnetic Waves
Electromagnetic waves consist of mutually perpendicular, oscillating electric and magnetic fields that also remain perpendicular to the direction of propagation. They travel through vacuum at the speed of light and include radio waves, microwaves, infrared, visible, ultraviolet, X-rays and gamma rays. Unlike mechanical waves, they do not require a material medium.
