Understanding UV Radiation
Ultraviolet (UV) radiation is a part of the electromagnetic spectrum emitted by the sun. It has shorter wavelengths than visible light, making it invisible to the naked eye. Despite its invisibility, UV radiation plays a critical role in various ecological processes and can also have significant effects on health.
Types of UV Radiation
- UV-A: Long-wave UV responsible for about 95% of the UV radiation reaching the Earth's surface.
- UV-B: Medium-wave UV, primarily responsible for sunburn and has a significant impact on DNA.
- UV-C: Short-wave UV, which is absorbed by the Earth's ozone layer and does not reach the surface.
Effects on Frogs and Amphibians
Frogs and other amphibians are highly sensitive to UV radiation, making them excellent bioindicators of environmental changes. Overexposure to UV-B radiation can lead to skin damage, decreased immune function, and reduced survivability in these creatures.
