Answer to: Calculate the wavelength of red light with a frequency of 4.62 \times 10^{14} \text{ s}^{ 1} . By signing up, you'll get thousands...
wavelength and speed of light are related to each other. And each parameter can have its own importance. Therefore the wavelength of red light from the above data we can say that it should be between 620-720nm. Basically, the value is taken as 680nm. And also the wavelength of violet l...
Here, the melatonin synthesis pathway in tomato fruit was completely elucidated. The functions of biosynthesis-related genes (SlSNAT,SlASMT5,SlASMT7,andSlCOMT2) were identified. We also found that red light treatment significantly promoted melatonin synthesis in tomato fruit via the SlphyB2-SlPIF4-...
A. Red B. Blue C. Green D. Violet 相关知识点: 试题来源: 解析 A。解析:在可见光光谱中,不同颜色的光波长不同。红色光的波长最长,约为620 - 750纳米。蓝色光的波长较短,绿色光波长处于中间,而紫色光波长最短。所以这题答案为A。反馈 收藏 ...

One of the most important properties of light waves is their wavelength. This refers to the distance between two adjacent peaks of the wave, and determines the color of light. Longer wavelengths appear red or orange, while shorter wavelengths appear blue or purple. The human eye can see a sm...
I mean, it is not red at all.It lies in the infrared range of the spectrum.We can't see it, but plants can sense it as a different wavelength.OK. Now I need to mention another thing about photosynthesis.I didn't explain how different wavelengths of light affect photosynthesis.When a ...
Light can be described using its wave nature or its particle nature. Light can be described as a transverse wave hence some properties typical of a wave can be used to describe light. These include its wavelength, frequency and energy.
“The technology is simple and very safe, using a deep red light of a specific wavelengththat is absorbed by mitochondria(线粒体) in the retina to supply energy. ()1. What is the author's main purpose in writing the text?A. To promote the finding.B. To teach people to do research....
