Yellow light travels through a certain glass block at a speed of 3 * 108 m/s . The wavelength of the light in this glass is 3.81 * 10 - 7m . What is the frequency?

f = 7.87×10¹⁴ Hz

Explanation:

Given data:

Speed of light = 3×10⁸ m/s

Wavelength of light = 3.81 ×10⁻⁷ m

Frequency of light = ?

Solution:

Formula:

Speed of wave = wavelength × frequency

Now we will put the values in formula.

3×10⁸ m/s = 3.81 ×10⁻⁷ m × f

f = 3×10⁸ m/s /  3.81 ×10⁻⁷ m

f = 0.787 ×10¹⁵ s⁻¹

   s⁻¹  = Hz

f =  0.787 ×10¹⁵ Hz

f = 7.87×10¹⁴ Hz

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
