while IR radiation has a longer wavelength and a weaker energy level. About 30 percent of the radiation striking Earth's atmosphere is immediately reflected back out to space by clouds, ice, snow, sand and other reflective surfaces, according toNASA. The remaining 70 percent of incoming solar ...

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...
What is the relationship among frequency, wavelength, and wave speed? 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 vel...
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...
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 ...
A tuning fork of frequency 100 Hz emits a wave of wavelength 4m. What is the temperature of the atmosphere, if the velocity of sound at 27∘C is 330m/s? View Solution For the series LCR circuit shown in the figure, what is the resonance frequency and the amplitude of the current at...
The wavelength is the distance between adjacent crests or identical points in the adjacent cycles of a waveform signal transmitted through space or along a wire. Soundwaves vibrate the air to send audio in through the outer ear to the ear drum, which vibrates to send sound information to 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...
Wavelength-division multiplexing (WDM) Multiple communications channels are consolidated and then transmitted on lightwaves with different wavelengths. Conceptually, this is similar to FDM, except that FDM is described in terms of frequencies -- radio or television broadcasting, for example -- whereas ...
