WebRed light has relatively long waves, around 700 nm long. Blue and purple light have short waves, around 400 nm. Shorter waves vibrate at higher frequencies and have higher … WebThis is incorrect. Blue light ( which is close to violet) has a higher frequency than red light as shown in this quote. “Visible light has a wavelength range from ~400 nm to ~700 nm. Violet light has a wavelength of ~400 nm, and a frequency of ~7.5*10 (14)Hz. Red light has a wavelength of ~700 nm, and a frequency of ~4.3*10 (14)Hz.”.

WebOct 16, 2024 · The wavelength of green light is longer than that of red light, which explains its higher frequency. Furthermore, because green light has a lower energy than red light, it is more likely to be absorbed by plants. Despite being less efficient than blue and red lights, green light is still required for photosynthesis.
WebThe most beneficial red light wavelength for skin is commonly considered to be 660 nm, which is near the upper range of visible red light. This wavelength has deeper penetration than the shorter 630 nm wavelength, with similar effects. Red wavelengths penetrate the skin and sebaceous glands to rejuvenate the skin’s tone and texture.
