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

sea breeze

explanation:

cool air is going towards land allowing for the land to be cooler, the hotter air gets pushed away from the land.
