1.)A photon has a wavelength of 1.95 x10^-11 m. What is the frequency?
Georgia [21]

Explanation:

Given parameters:

Wavelength of photon = 1.95 x 10⁻¹¹m

Unknown:

Frequency of the wave  = ?

Energy of the photon = ?

Solution:

The frequency and wavelength of a wave are related by the expression;

   C = Fλ

C = speed of light  = 3 x 10⁸m/s

F = frequency

λ = wavelength

 Insert the parameters and solve;

    3 x 10⁸  = F x 1.95 x 10⁻¹¹

       F  = \frac{3 x 10^{8} }{1.95 x 10^{-11} }   = 1.54 x 10¹⁹Hz

Energy of the photon is related to frequency using the expression below;

  E  = hF

h is the Planck's constant = 6.634 x 10⁻³⁴m²kg/s

Insert the parameters and solve;

    E = 6.634 x 10⁻³⁴ x 1.54 x 10¹⁹   = 1.02 x 10⁻¹⁴J

What kind of Romance Novels would kids between the age of 14-18 read. Whether it is an actual book or a book made on sites like
alexdok [17]
A book series that a 14-18 year old would read could be the books by Sarah Mlynowski. A book that I have read that is really good it Gimme A Call. It is based on a girls point of view. It is fiction because of the idea that the book revolves around the character getting a call from her future self telling her to do things differently with her life. The book isn't mainly about romance, but it does have some really good topics that teens can deal with. Also, when you are looking for a romance novel keep in mind that there are different levels of romance books. There are the type of books where there is only flirting and the usual teenage dating, but then there are books with very, and I mean very, unpleasing scenes.
