Determine the frequency of light with a wavelength of 4.257x10^-7cm
TEA [102]

Answer:

frequency of light is 70.47\times 10^{15} \ per\ second

Explanation:

Given

wavelength of light = 4.257\times 10^{-7}\ cm = 4.257\times 10^{-7} \times 10^{-2} \ m= 4.257\times 10^{-9}\ m

Speed of Light = 3\times 10^8 \ m/s

∴ Frequency of Light = \frac{\textrm{Speed of Light}}{\textrm{wavelength}}=\frac{3\times 10^8}{4.257\times 10^{-9}}= 70.47\times 10^{15} \ per\ second

Answer:

Gas to Solid

Explanation:

A condensation reaction goes from gas to solid

Condensation is a physical change which alters the physical properties of matter particularly the form and state. In a condensation reaction, a gas goes from solid to liquid.

It is the inverse of the sublimation reaction.

  • It involves the loss in energy by a gas.
  • When gases lose energy, they become pulled together by attractive forces.
  • This changes their state to solid with enough loss in energy.
