One thing to note is that currently, noise-canceling headphones are only able to actively cancel out low-frequency sounds. Because high-frequency sound has a shorter wavelength than low-frequency sound, canceling this sound would require either the locating devices be closer to the listener's eard...
blue light is a high-energy visible light that is emitted by electronic devices and artificial lighting sources. it has a short wavelength and can penetrate deep into the eye, potentially causing eye strain, dryness, and fatigue. additionally, exposure to blue light, especially in the evening ...
When the microphone is close to the sound source, i.e. the distance is comparable to the wavelength, the sound arriving looks more like a ‘spherical wave’. Under these conditions, the difference in pressure between the front and back of the microphone diaphragm becomes greater towards low fr...
Waveguide Size:Waveguide components are available in various sizes. To function properly the waveguide must have a certain minimum cross section, relative to the wavelength of the signal. If the wavelength of the signal is too long compared to the cross-sectional area the waveguide the signal will...
Any changes to the electromagnetic wavelength will effect the movement of the electrons; for example, if you increase the voltage of the accelerating electron beam, you will increase the image resolution. When the energetic electrons come in contact with the sample, the reaction(s) provide informat...
What Is mmWave?The term millimeter wave or mmWave refers to a part of the radio frequency spectrum approximately between 20 GHz and 100 GHz, which has a very short wavelength. This section of the spectrum is lightly used, so the recent allocation of 3GPP FR2 and FR3 bands has generated ...
With this experimental approach, we can change the environmental conditions. We can change, for example, the water temperature, we can change the wavelength of the imaginary sun that we're using…通过这种实验方法，我们可以改变环境条件。例如，我们可以改变水温，我们可以改变我们正在使用的假想太阳的波长...

can be destroyed/created when radiation is absorbed/emitted.当辐射被吸收或释放时可以被摧毁或创造。 can have particle-like interactions (i.e. collisions) with electrons and other particles, such as in the Compton effect. 可以和电子和其他的粒子有粒子状的相互作用(即碰撞),如康普顿效应。
This effect may be highly polarization-dependent. Sometimes this is a drawback, but in other cases it is specifically exploited to either separate or combine orthogonal polarizations. A beamsplitter can also be wavelength dependent. In this case, it might be used to separate two co-axial laser...
