Doss [256]
<h2>Phenocrysts and Porphyritic texture </h2>

Explanation:

  • The early formed crystals are of phenocrysts and the texture of these crystals is porphyritic texture.  
  • This crystallization occurs when early-forming plagioclase crystals which are rich in calcium start coating with plagioclase crystals which are rich in sodium.
  • On cooling, the magma is then processed in a volcanic eruption, after the eruption the liquid which is left behind will start cooling and forms a porphyritic texture.

A local am radio station broadcasts at a wavelength of 349m, calculate the energy of the wavelength at which it is broadcasting?
Juli2301 [7.4K]

Answer:

E = 5.69x10⁻²⁸m

Explanation:

To solve this question we neeed to convert the wavelength in meters to energy in joules using the equation:

E = hc / λ

<em>Where E is energy in joules, h is Planck's constant = 6.626x10⁻³⁴Js</em>

<em>c is light constant = 3.0x10⁸m/s</em>

<em>And λ is wavelength in meters = 349m</em>

Replacing:

E = 6.626x10⁻³⁴Js*3.0x10⁸m/s / 349m

E = 5.69x10⁻²⁸m

Which produces wave particles that move and displace one another? A) a radio B) a guitar C) a light bulb D) a microwave oven
Semmy [17]
The answer is B. A guitar generally produces sound waves that propagate when the strings are strummed. The strings are displaced through the vibrations caused by contact of the hand and the guitar. You will also notice the vibrations by looking closely to the string. Wave particles continuously collide with each other to make a sustaining or prolonging sound.
