Wavelength is a concept most often used to describe sinusoidal or nearly sinusoidal waves because it does not get deformed during its propagation and, hence, the laws of a linear system can be applied on it wherever in space. Wavelength is a characteristic of a wave in space, which also ...
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...
The Tyndall effect occurs when particles within a colloid or suspension scatter the light that passes through. The intensity of the scattering is a direct result of the size of the colloidal particles; since they are roughly the size of a single wavelength of light, the Tyndall effect is much...

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。

What is the wavelength of a wave that has a speed of 30 m/s and a frequency of 6.0 hz? How does the Doppler effect affect amplitude? If a wave has a frequency of 5000 Hz and wavelength of 5 cm, what is the velocity of the wave? What is the frequency of a wave? What does the...
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...
X-ray is an electromagnetic wave with extremely short wavelength and high energy, which has very strong penetrating ability. When an X-ray irradiates a sample, its transmission intensity is not only related to the energy of the X-ray, but also related to the material density and thickness of...
The greenhouse effect occurs when Earth's atmosphere traps solar radiation because of the presence of certain gases, which causes temperatures to rise.
