What else can I help you with?
How are phytoplankton affected by UV radiation?
Ozone depletion allows the UV rays to come in. These rays kill the planktons.
Which are more energetic photons of UV-A radiation or photons of UV-B radiation?
Photons of UV-B radiation are more energetic than photons of UV-A radiation. UV-B radiation has shorter wavelengths and higher energy levels compared to UV-A radiation. UV-B radiation is classified as potentially harmful to human health, while UV-A radiation is less energetic and is more commonly associated with tanning and aging effects on the skin.
Which are more energetic photons of UV A radiation or photons of UV B radiation?
Photons of UV B radiation are more energetic than photons of UV A radiation. UV B radiation has a shorter wavelength and higher energy compared to UV A radiation, making it more damaging to the skin and eyes.
What is ultraviolet radiation where does it come from what is uv index and how is the uv index determine?
Ultraviolet (UV) radiation is a type of electromagnetic radiation that comes from the sun and can also be produced by artificial sources like tanning beds and some lamps. The UV index measures the level of UV radiation from the sun at a particular place and time, which helps to inform people about the potential risk of harm from sun exposure. The UV index is determined based on factors like the angle of the sun, cloud cover, and ozone levels in the atmosphere.
Which of these is not a reason to avoid UV radiation?
uv radiation destroys vitamin D
Does ozone reflect or absorb UV radiation?
Ozone absorbs UV radiation.
What kinds of radiation come from the sun?
The sun emits three main types of radiation: visible light, ultraviolet (UV) light, and infrared (heat) radiation. Visible light enables us to see, UV light can cause sunburns and skin damage, while infrared radiation warms the Earth.
Are UV light and UV rays the same thing?
They’re basically referring to the same part of the electromagnetic spectrum, but the terms are used a little differently. UV rays usually refers to ultraviolet radiation coming from sources like the sun or UV lamps. **UV light** is a more general term often used when talking about UV devices or applications. UV is divided into three main ranges: UVA, UVB, and UVC. UVC is commonly used in applications such as water and air treatment because it can inactivate many microorganisms.
What happened when uv radiation emitted sodium?
UV radiation does not and cannot emit sodium.
Which does not belong vitamin D cholesterol UV radiation or keratin?
Hemoglobin
Which of the following substances absorbs UV radiation?
The substance that absorbs UV radiation is ozone.
Does the ozone layer reflect or absorb UV radiation?
The ozone layer absorbs UV radiation.
