255 Which coloured light, red or violet, has a higher frequency and which one has a longer wavelength?B Higher frequency Longer wavelength A violet violet B violet red C red violet D red red 相关知识点: 试题来源: 解析 BUsing infra-red radiation and ultra-violet as reference red light will...
Each color of light has a different wavelength. Key VocabularyWavelength: The wavelength is the distance that exists between a wave in its periodic disturbance over the travel cycle. It is directly associated with any periodic wave. Frequency: Frequency is defined as the number of repetitions of...
Therefore, the optical recording medium can be compatible with a compact disc (CD) and have a high reflectivity at longer wavelength than 600 nm.Kyung-sun MinSung-Hoon KimYoung-jae HuhSoo-hyung LeeUSUS5955168 * Aug 8, 1997 Sep 21, 1999 Samsung Electronics Co., Ltd. Optical recording ...
A sound wave and an electromagnetic wave have the same frequency. Which has the longer wavelength? How does the frequency of the resulting sound compare with the frequency of the standing wave in the string? Consider the waveform expression. y(x,t) =...
When the light goes through a raindrop, these colors can separate out.Each of the colors in the rainbow has a different"wavelength(波长)". Raindrops look like little balls.When light hits one of these little balls of water, the light can change direction. We call this "refraction(折射)"...
<p>To solve the question regarding which rays have a greater wavelength than visible light, we can follow these steps:</p><p>1. <strong>Understand the Electromagnetic Spectrum</strong>: The electromagnetic spectrum is a range of all types of electrom
This wavelength stability requires the laser diode temperature to be controlled and often the laser diode to include an additional wavelength stabilizing element. This element is generally a FBG (Fiber Bragg Grating) for single mode laser diodes (a specialized piece of fiber situated roughly 1 meter...
Predict the complex which absorbs the longer wavelength. In the given complex ions, the ligandH2Ois a weak field ligand; also the crystal field splitting is less than the ligandNH3which requires less energy (long wavelength) to promote the electrons from the lower...
The invention relates to a titanium oxide-based polymer composition. The inventive composition comprises a TiOx(OH)y(H2O)z (x+y+z=3) titanium oxide-based polymer in the form of a gel or sol. Said polymer, which has a one-dimensional (1D) structure, is made from concentrically-wound fibe...
to be used in a low frequency region with a low loss and which is provided with a same structure as a mixer which has a wide band twice or more the frequency of a millimeter or more wave while keeping a characteristic of a high integration array antenna, which makes most of the high ...
