Answer:
It says energy can't be created or destroyed
Explanation:
Answer:
The angle between the red and blue light is 1.7°.
Explanation:
Given that,
Wavelength of red = 656 nm
Wavelength of blue = 486 nm
Angle = 37°
Suppose we need to find the angle between the red and blue light as it leaves the prism


We need to calculate the angle for red wavelength
Using Snell's law,

Put the value into the formula



We need to calculate the angle for blue wavelength
Using Snell's law,

Put the value into the formula



We need to calculate the angle between the red and blue light
Using formula of angle

Put the value into the formula


Hence, The angle between the red and blue light is 1.7°.
The magnetic field of the wire will be directed towards west. Using right thumb rule one can get the direction of field lines.
Answer:
The wavelength of the light is 555 nm.
Explanation:
according to Bragg's law..
n×λ = d×sin(θ)
n is the fringe number
λ is the wavelength of the light
d is the slit separation
θ is the angle the light makes with the normal at the fringe.
Oil is optically denser than water. When sound/light goes from optically denser medium to optically rarer medium, their velocity increase and they moves away for normal.

The sound wave speeds up and bends

As, In optics we learnt that light undergoes refraction when travels from medium of different densities. Similarly, Sound also follows the law of refraction.
- It is due to the change of speed of water in different mediums, This makes it speed up or down depending upon the medium and their densities.
