Which type of UV radiation is known as the "burning rays"?

  1. UVA radiation

  2. UVC radiation

  3. UVB radiation

  4. Infrared radiation

The correct answer is: UVB radiation

The choice identifying UVB radiation as the "burning rays" is correct due to the specific effects this type of ultraviolet light has on the skin. UVB radiation is primarily responsible for causing sunburn and contributes to the risk of skin cancer. It operates at a shorter wavelength compared to UVA radiation, which penetrates the skin more deeply and causes aging. Understanding the role of UVB is important for anyone involved in esthetics, as it highlights the necessity of using appropriate sun protection measures, such as broad-spectrum sunscreens, when exposed to sunlight. UVA radiation, while also harmful, is more associated with long-term skin damage and aging rather than immediate burning. UVC radiation generally does not reach the Earth's surface due to the atmosphere filtering it out. Infrared radiation is not classified as UV radiation and is primarily associated with heat rather than skin damage. This context reinforces the specific classification of UVB as the type known for its immediate harmful effects on the skin.
