Is alliteration a sound device or an image device?
Is alliteration a sound device or an image device?
Alliteration is a sound device involving consonant sounds not to be confused with consonance. In alliteration, the repeated consonant sounds appear at the initial letter of words and are discernible. Alliteration often occurs unintentionally but can be used intentionally for emphasis and sound effects.
What is alliteration as a sound device?
alliteration, in prosody, the repetition of consonant sounds at the beginning of words or stressed syllables. Sometimes the repetition of initial vowel sounds (head rhyme) is also referred to as alliteration. As a poetic device, it is often discussed with assonance and consonance.
How do you use an alliteration?
Alliteration is the repetition of the same sound or letter at the beginning of each or most of the words in a sentence. The easiest way to use alliteration would be to repeat the starting letter of the words.
What is an example of an X-ray telescope?
Examples of X-ray telescopes of this types includes Einstein , ROSAT and Chandra , which was launched in 1999. However, due to the thick and massive mirror substrates, these mirrors generally have limited collecting areas, especially at higher energies, due to the limited nestings of shells allowed.
Why is the X-ray telescope mounted in a parallel line?
For this reason, the mirrors in X-ray telescopes are mounted with their surfaces only slightly off a parallel line with the incoming X-rays. Application of the grazing-incidence principle makes it possible to focus X-rays from a cosmic object into an image that can be recorded electronically.
How do X-ray telescopes get above the Earth’s atmosphere?
In order to get above the Earth’s atmosphere, which is opaque to X-rays, X-ray telescopes must be mounted on high altitude rockets, balloons or artificial satellites .
Why are X-ray telescopes not as good as optical telescopes?
Although the spatial resolving power of a telescope depends inversely on photon wavelength, the practical difficulty in bringing X-rays to focus means that the spatial resolution of X-ray telescopes is generally much worse than for an optical telescope of similar collecting area.
