The light energy produced by the fire can be seen easily by naked eyes; therefore, fire is one of the best examples of visible light in real life. 4. Glow Sticks. The light that is radiated by the glow sticks into the environment can be seen easily by naked eyes and therefore, is yet another example of visible light in real life.

Mar 9, 2021 · According to standard definitions this includes the wavelengths from 380 to 750 nanometers. However, some people can see some ultraviolet and near infrared such that this range could be extended to about 310 to 1100 nanometers. The following are common examples of visible light followed by a chart of the basic colors by wavelength.
- Radio. 300 gigahertz and lower. Radars, broadcasting, satellites, wireless networks, navigation and more. Planet to building-sized.
- Microwaves. Between 300 megahertz and 300 gigahertz. Weather radar, microwave cooking, broadcasting, wireless communication. Person to insect-sized.
- Infrared. Between 300 gigahertz and 430 terahertz. Thermal imagine, communication, spectroscopy, astronomy. Pinpoint. You’ve probably seen infrared light used in night vision cameras.
- Visible Light. Between 400 terahertz and 790 terahertz. Vision, digital screens, lamps, LEDs, traffic lights, skin therapy, phototherapy.
Jan 10, 2024 · Photosynthesis. The very first on my list of 10 practical examples and uses of visible light in everyday life is for the process of photosynthesis and plant growth. Visible light is vital for photosynthesis, enabling plants to convert light energy into glucose and oxygen. Chlorophyll absorbs blue and red light most effectively, driving chemical ...
Dec 7, 2022 · Light has the properties of waves. Like ocean waves, light waves have crests and troughs. The distance between one crest and the next, which is the same as the distance between one trough and the next, is called the wavelength. The frequency of a wave is the number of crests (or troughs) that pass a point in one second.
Dec 29, 2017 · Benefits for Life. 1. Photosynthesis for Food formation. The energy from light is trapped as chemical energy and stored as food. As you might have known, this occurs through a process called photosynthesis. Photosynthesis is a concept in biology wherein food is synthesized in green leaves in the presence of light.
