True or False: Shorter wavelengths have more energy than longer wavelengths.

• A. True
• B. False
• C. Depends on the mediums
• D. Only true for visible light

Answer: (A)

The statement is true: shorter wavelengths have more energy than longer wavelengths. This relationship can be understood through the principles of wave physics, particularly in the context of electromagnetic radiation. The energy of a photon is inversely proportional to its wavelength, which means that as the wavelength decreases, the energy increases. This can be mathematically represented by the equation ( E = \frac{hc}{\lambda} ), where ( E ) is energy, ( h ) is Planck's constant, ( c ) is the speed of light, and ( \lambda ) is the wavelength.

In the electromagnetic spectrum, as you move from longer wavelengths — such as radio waves — to shorter wavelengths, such as ultraviolet and gamma rays, the energy of the photons increases significantly. This principle is fundamental in various fields, including physics and biomedical applications, as it affects how different types of radiation interact with matter.

The other options are not accurate because they either suggest conditions under which the relationship might not hold (as in "depends on the mediums") or incorrectly limit the scope of the statement to "visible light" when the principle applies universally across all forms of electromagnetic radiation.
