Answer:
Ultraviolet light has a shorter wavelength than infrared light.
Explanation:
Electromagnetic waves are waves that does nor require material medium for their propagation. Example of Electromagnetic waves are classified according to the acronym RIVUXG. They decrease in wavelength and increase in frequency from Radiowaves to Gamma ray.
R is the Radio waves
U - ultraviolet ray
V - Visible light (ROYGBIV){Red, Orange, Yellow, Green, Blue, Indigo and Violet}
Note that the visible light also decrease in wavelength from red to indigo, therefore red will have longer wavelength compare to blue light.
I - Infrared rays
X - X ray
G - Gamma ray
Based on the above conclusion, it can be inferred that Ultraviolet light has a shorter wavelength than infrared light since Infrared rays comes before the infrared light in the electromagnetic spectrum.
Answer:
Increase in the intensity of pressure allows very less deformation
Explanation:
For the water the variation of pressure at any depth is directly proportional to the depth of the water above that level.
Thus, at depth greater than 60 m the intensity of pressure on ice is very high and therefore very little deformation is possible.
Hence, the transition from brittle to ductile behavior is observed.
-- If the frequency of a wave is too high for our eyes to detect it ... but not <u>too too</u> high ... we call it an <em>ultraviolet </em>wave.
-- If the wave's frequency is even higher than that, we call it an <em>X-ray</em> wave.
-- If the wave's frequency is even higher than that, we call it a <em>Gamma Ray </em>wave.
Answer: The complexity of filter is the order of the filter. Greater the order of the filter, more efficient the filter is. Roll of value of one filter is 20dB/dec. So the roll-off value of 8th order filter is 160dB/dec. 8th order filter is more efficient than the second order low-pass filter.
