Visible light is both harmful and helpful. It provides us with the ability to see and is essential for many biological processes, but excessive exposure to certain wavelengths of visible light can also cause damage to our eyes and skin.
Glass is transparent to visible light but absorbs ultraviolet (UV) radiation. This is why glass can protect against UV rays from the sun, which can be harmful to both humans and materials.
Ultraviolet (UV) light is helpful because it plays a role in the synthesis of Vitamin D in our bodies and can be used for disinfection purposes. However, excessive exposure to UV light can damage skin cells, leading to premature aging and an increased risk of skin cancer. It is important to balance the benefits and risks of UV light exposure.
Electromagnetic radiation is a type of energy that travels through space in the form of waves. Ultraviolet light is a specific type of electromagnetic radiation that has shorter wavelengths and higher energy than visible light. Exposure to ultraviolet light can have both beneficial (such as vitamin D synthesis) and harmful effects (such as skin damage).
Ultraviolet (UV) light is a type of electromagnetic radiation with shorter wavelengths than visible light. It is often divided into UVA, UVB, and UVC rays based on their wavelengths. UV light is present in sunlight and can have both beneficial effects, such as vitamin D production in the skin, and harmful effects, such as sunburn and skin cancer.
Both are examples of electromagnetic radiation. Infrared has a longer wavelength (lower frequency) than visible light. Of course visible light is visible to humans and infrared is not (although long wave Infrared is sensible to humans as heat).
Sandpaper is both helpful and harmful.
they are helpful because they are
They are more helpful than harmful. My two gerbils are both helpful. They've helped me in many ways and so that's why I say they're more of helpful than harmful.
Both
both
Both only when it infects it is harmful
They are helpful because they clean out intestines. they are harmful because they can cause diseases
computer.. both helpful and not..
Bacteria can be both harmful and helpful. Harmful bacteria can cause diseases in humans, animals, and plants. However, some bacteria are beneficial and play important roles in processes like digestion, nutrient cycling, and decomposition.
a bacillus bacteria
If they are ecosystem?
Both. It depends what type of octopus it is.
