Answer:

Wavelength of light is 750 nm.

Explanation:

It is given that,

Frequency of light, \nu=4\times 10^{14}\ Hz

The relationship between the wavelength and the frequency of light is given by :

c=\nu\times \lambda

Where

c = speed of light

\nu = frequency of light

\lambda = wavelength of light

\lambda=\dfrac{c}{\nu}

\lambda=\dfrac{3\times 10^8\ m/s}{4\times 10^{14}\ Hz}

\lambda=7.5\times 10^{-7}\ m

\lambda=750\ nm

Hence, the correct option is (d) "750 nm".

pickupchik [31]

Answer:

a

The focal length of the lens in water is  f_{water} = 262.68 cm

b

The focal length of the mirror in water is  f =79.0cm

Explanation:

From the question we are told that

    The index of refraction of the lens material = n_2

    The index of refraction of the medium surrounding the lens = n_1

 

The lens maker's formula is mathematically represented as

            \frac{1}{f} = (n -1) [\frac{1}{R_1} - \frac{1}{R_2}  ]

Where f is the focal length

            n is the index of refraction

            R_1 and R_2 are the radius of curvature of sphere 1 and 2 of the lens

From the question When the lens in air  we have  

           \frac{1}{f_{air}} = (n-1) [\frac{1}{R_1} - \frac{1}{R_2}  ]

    When immersed in liquid the formula becomes

          \frac{1}{f_{water}} = [\frac{n_2}{n_1} - 1 ] [\frac{1}{R_1} - \frac{1}{R_2}  ]

The ratio of the focal length of the the two medium is mathematically evaluated as

           \frac{f_water}{f_{air}} = \frac{n_2 -1}{[\frac{n_2}{n_1} - 1] }

From the question

      f_{air }= 79.0 cm

       n_2 = 1.55

and the refractive index of water(material surrounding the lens) has a constant value of  n_1 = 1.33

         \frac{f_{water}}{79}  = \frac{1.55- 1}{\frac{1.55}{1.44}  -1}

           f_{water} = 262.68 cm

b

The focal length of a mirror is dependent on the concept of reflection which is not affected by medium around it.

if an objects first movement is 3.0m North and another movement is 4.0m West, what is the magnitude of the displacement made ove
Snezhnost [94]

If an object's first movement is 3.0m North and another movement is 4.0m west, the magnitude of the overall displacement made would be 5.0 meters in the northwest direction.

<h3>What is displacement?</h3>

Displacement is a vector quantity. This indicates that it has both a direction and a magnitude and that it is visually represented as an arrow that points from the starting position to the ending position.

As given in the problem if an object's first movement is 3.0m North and another movement is 4.0m west

Resultant displacement can be calculated with the help of the triangle law of the vector addition,

Resultant = √( 3² + 4²)

                =√25

                = 5.0 m

Thus, the magnitude of the overall displacement made would be 5.0 meters in the northwest direction.
