The refractive index of water is 
. This means that the speed of the light in the water is:
The relationship between frequency f and wavelength
of a wave is given by:
where v is the speed of the wave in the medium. The frequency of the light does not change when it moves from one medium to the other one, so we can compute the ratio between the wavelength of the light in water
to that in air as
where v is the speed of light in water and c is the speed of light in air. Re-arranging this formula and by using
, we find
which is the wavelength of light in water.

Answer:
66.4 N
Explanation:
From Newton's second law, <em>F </em>=<em> ma</em>
where <em>F</em> is the force, <em>m</em> is the mass and <em>a</em> is the acceleration.
Because the object has acceleration in two directions and the mass is constant, the force will be in two directions. The component of the forces are:
The magnitude of the resultant force is given by
