Coherent light with wavelength 540 nm passes through narrow slits with a separation of 0.370 mm .Part AAt a distance from the sl

77julia77 [94]

Answer:

The phase difference between waves 31.7 rad

Explanation:

Given :

Wavelength $\lambda = 540 \times 10^{-9}$ m

Separation between two slit $d = 0.370 \times 10^{-3}$ m

Angle $\theta =$ 25°

From the formula of phase difference,

$\delta = \frac{2\pi d }{\lambda} \sin \theta$

Where $\delta =$ phase difference

$\delta = \frac{2 \times \pi \times 0.370 \times 10^{-3} }{540 \times 10^{-9} } \sin 25$

$\delta = 31.7$ rad

Therefore, the phase difference between waves 31.7 rad

Explain why 15yr old need more calcium than adults

Tom [10]

Answer:

When adolescents get enough calcium during the teen years, they can start out their adult lives with the strong bones and significantly reduce their risk for fractures as an adult. Inadequate calcium intake during adolescence and young adulthood puts individuals at risk for developing osteoporosis later in life.

You have given a power supply, copper wire, and an iron nail. What should you do to decrease the strength of the electro magnet?

Viefleur [7K]

Explanation:

If you wrap some of the wire around the nail in one direction and some of the wire in the other direction, the magnetic fields from the different sections fight each other and cancel out, reducing the strength of your magnet

Does a spherical bubble of air in a volume of water act to converge or to diverge light passing through it?

viktelen [127]

Answer:

diverge light

Explanation:

The refractive index of water is greater than that of air which means that water is more denser than air and also air is optically rarer than water.

Thus,

When the beam of the light is incident from the air to the bubble which contains air, the light bends away from the normal and then the light travels from air to water and bend towards the normal. Thus, the light is first bend away from the normal and then towards the normal which means that the bubble has diverging nature. The light will likely to diverge.

A image is shown below for better understanding.
