What statement about UVB radiation is true?

It is less harmful than UVA radiation
It has a longer wavelength than UVA radiation
It has more energy than UVA radiation
It is only present in tanning beds

The correct answer is: It has more energy than UVA radiation

The statement that UVB radiation has more energy than UVA radiation is accurate because UVB rays, which are primarily responsible for causing sunburn and contributing to skin cancer, have a higher energy level due to their shorter wavelength. The energy of radiation is inversely related to its wavelength; thus, shorter wavelengths correspond to higher energy levels. In contrast to UVA, which penetrates the skin more deeply and is associated with skin aging and some forms of skin cancer, UVB has a more direct impact on the skin's surface, leading to damage. Understanding this distinction is crucial for estheticians when educating clients about sun protection and the different effects of UV radiation on skin health.
