the highest directly measured frequency is 5.20 x 10^14 Hz, corresponding to one of the transitions in iodine-127. How many wavelengths of electromagnetic waves with this frequency could fit across a dot on a book page? Assume the dot is 2.00 x 10^-4m in diameter.

Respuesta :

Ī» = 5.7 X 10ā»ā·m

On using quantum dot, it is 351

Explanation:

Given-

Frequency, f = 5.20 x 10^14 Hz

Speed of light, c = 3 X 10āø m/s

Wavelength, Ī» = ?

We know,

Ī» f = c

Ī» = c / f

Ī» = [tex]\frac{3 X 10^8}{5.2 X 10^1^4}[/tex]

Ī» = 5.7 X 10ā»ā·m

Dot = 2 X 10ā»ā“

So,

2 X 10ā»ā“ / 5.7 X 10ā»ā·m = 351
