(I) How does the refractive index of a medium depends on the wavelength of light used? (II)Which is greater, angle of incidence or angle of refraction, when light travels from denser medium to rarer medium. View Solution Doubtnut is No.1 Study App and Learning App with Instant Video Solu...
Center wavelength of an optical signal The center wavelength is the wavelength measured at the midpoint of a half-amplitude line in the transmit spectrum. Lasers of different types or two lasers of the same type may have different center wavelengths due to factors such as techniques and productio...
Does gravity travel at the speed of light? What is the speed of light in air? How far in terms of wavelength does a wave travel in one period? Does time exist at the speed of light? How fast do primary waves travel? Can humans travel at the speed of light?
In brief, MoS2-SS-HA nanosheets watery solution (0.5 mg/mL) was mixed with different concentrations of Er which were dissolved in DMSO solution and stirring the mix- ture for 24 h (pH = 7.0). Excess Er was removed by cen- trifugation at 4000 rpm for 20 min. The...
When light enters one medium from another it experiences a change in direction. This phenomenon is known as refraction, and is defined through Snell's law {eq}n_{1}sin(\theta_{1}) = n_{2}sin(\theta_{2}) {/eq}. In Snell's law θ1 is the incident angle, θ2 is the refracted...
1) is one example of a phosphonate (called bisphosphonate) being used as a drug for the treatment of osteoporosis, as a scale and corrosion inhibitor in water treatment, and as an antioxidant in cosmetics. Hence, a single phosphonate compound may have many different uses and applications.9 ...
光盘都有什么格式（What format does the CD have）CD-R and CD-RW of the main recording format As we all know, burning principle and CD-R CD-RW are roughly the same, the difference is whether repeated burn on the disc, and write on a disk file format is exactly the same. We can put...
Climate change has increased wildfire activity in the western USA and limited the capacity for forests to recover post-fire, especially in areas burned at high severity. Land managers urgently need a better understanding of the spatiotemporal variability in natural post-fire forest recovery to plan ...
However, some of the signal within the fiber is lost as it travels longer distances. The extent that the signal degrades depends on the purity of the glass, the number of bends in the fiber or splices that connect sections of fiber and the wavelength of the transmitted light. For example...
Thegreencolor was created by analyzing the way the rods and cones in our eyes are stimulated by different wavelengths of light. The company found that the human eye is most sensitive to light at a wavelength of 555 nanometers—a bright green. ...
