What effect does a high level of UV light have on phytoplankton?
the UV light kills single-celled organisms
Where to get uv light bulbs?
UV lamp, also called Black-light Lamp, device for producing electromagnetic radiations in the wavelengths between those of visible light and X-rays. The Sun's rays are rich in such radiation, sometimes referred to as black light because it is not visible to the unaided eye.
How do Plant light bulbs work?
The fluorescent type of light bulbs (correctly called lamps) have a phosphor that besides emitting visible light (400 to 750 nm) also emits some UV enengy in the UV-A range. Plants need visible light and some UV-A to be effective.
What are the best brands of UV light bulbs?
The best UV light bulbs are made by Sylvania and Philips. The downside of the story is that UV light bulbs of those brands are among the most expensive on the market.
Which rays of the sun can in high quantities damage the skin?
UV RAYS!!! The sun is the major natural source of UV Rays. UV Rays are invisable. They are still a form of light rays. UV stands for Ultra Violiet Rays. These (UV) rays cause sunburn and damage the eyes. Overexposure of UV Rays can cause serious skin cancer. UV Rays, however, can have useful effects, too. They can destroy harmful organisms.

Can UV light radiation effect growth?
Yes. Plant life is known to benefit from UV light. An example is people who grow their own marijuana indoors under UV lights.
What is the reason of incubating the UV-exposed cells in the dark environment?
cell that survive DNA damage due to the effect of the UV LIGHT only can growth in dark environment.
What type of electromagnetic wave is used to sterilize?
Ultraviolet (UV) light is commonly used to sterilize surfaces and equipment. UV light has a germicidal effect that can inactivate bacteria, viruses, and other microorganisms by damaging their DNA or RNA. UV light can be effective for sterilization when used at specific wavelengths and durations.
What can you infer about the UV rays?
They stimulate bacteria growth or They are beneficial to the water molecules.
Does UV light sterilize utensils?
UV light radiation kills bacteria and can sterilize utensils (UV rays are used to sterilize goggles in the laboratory, for example.
What effect does a high level of UV light have on phytoplankton?
the UV light kills single-celled organisms
What effect does high levels of UV light have on phytoplankton?
the UV light kills single-celled organisms
Why is the reasonfor using UV light in butcheries?
UV light is used in butcheries to disinfect surfaces and equipment, as it can kill bacteria, viruses, and other microorganisms. This helps to ensure food safety and prevent contamination of meat products. UV light is an effective and environmentally friendly way to reduce microbial growth in food processing environments.
How does ultraviolet light kill bacteria?
UV light causes dimerisation between Cytosine bases in DNA (causing it to mutate). As bacteria only have small genomes, mutations will have a lethal effect a lot more commonly than if it happened to a person.
Which part of the em spectrum can be used to kill bacteria?
Ultraviolet (UV) radiation, specifically UVC light, can be used to kill bacteria. UVC light has a short wavelength and high energy, which damages the DNA and RNA of bacteria, preventing their growth and reproduction. This property makes UVC light an effective tool for disinfection purposes.
What is the effect of longer exposure to ultraviolet light?
Longer exposure to ultraviolet (UV) light can increase the risk of sunburn, skin aging, and skin cancer. It can also damage the DNA in skin cells, leading to mutations that can cause skin cancer. It's important to protect your skin from excessive UV exposure by using sunscreen, wearing protective clothing, and seeking shade.
Does UV light kill bacteria?
yes, it does it burns it until it goes away.
