Ultraviolet rays are potentially harmful to us due to their intensity. This is what is known as the amplitude of the rays from the sun.
Ultraviolet rays are potentially harmful to us due to their high frequency. UV rays have shorter wavelengths and higher frequencies compared to visible light, which can damage the DNA in our skin cells and lead to conditions like sunburn, skin aging, and skin cancer.
The ozone layer blocks most of the sun's harmful ultraviolet rays. The ozone layer has thinned over time in certain areas due to emissions of ozone depleting chemicals widely used in industry.
ability to damage our skin cells and DNA, leading to premature aging and an increased risk of skin cancer. UV rays can also weaken our immune system and cause eye damage over time.
Some harmful electromagnetic waves include ultraviolet rays, X-rays, and gamma rays due to their ability to damage living cells through ionization. Others, such as visible light and radio waves, are typically not harmful because they have lower energy levels that do not cause ionization.
due to some ultraviolet rays from sunlight.
Radio waves, visible light, infrared rays, and the waves that heat food in a microwave oven are forms of electromagnetic energy, due to varying wavelengths and frequencies. Ultraviolet rays and X-rays are forms of ionizing radiation, which have higher energy levels and can impact living tissue at the cellular level, making them potentially harmful in excess.
More harmful ultraviolet rays are reaching Earth's surface due to ozone layer depletion caused by human activities like the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances. This depletion allows increased levels of UV radiation to penetrate the atmosphere and reach the surface, leading to negative effects on human health and the environment.
Flavonoids found in plants act as UV-absorbing compounds, which help to protect the leaves from damage due to ultraviolet light. They help to filter out harmful UV rays and prevent oxidative stress that can lead to cellular damage. This protective mechanism allows the plant to maintain its photosynthetic efficiency and overall health.
The ozone layer began shielding Earth from ultraviolet rays approximately 2 billion years ago when oxygen levels in the atmosphere increased due to the rise of photosynthetic organisms. The ozone layer helps to absorb the majority of the Sun's harmful UV radiation, protecting life on Earth from its damaging effects.
it is because when they deplete the ozone layer they attributes to the increasing of the ozone hole and allow the ultraviolet rays to reach the earth. due to ozone depletion, not only temperature increases but also level of water that result into floods.
Electromagnetic waves with frequencies higher than ultraviolet rays but lower than gamma rays are X-rays. X-rays have wavelengths shorter than ultraviolet radiation, allowing them to penetrate solid objects and tissues. They are commonly used in medical imaging and therapy due to their ability to penetrate matter.
The harmful ultraviolet radiations are the ones that try to enter into earth's surface . But due to the ozone layer, they are not allowed to enter.
