Leviafan [203]2 years ago
5 0

Answer:

Newton passed sunlight through a glass prism to separate the colors into a rainbow spectrum. He then passed sunlight through a second glass prism and combined the two rainbows. The combination produced white light. His simple experiment proved conclusively that white light is a mixture of colors.

aliina [53]

Answer:

Technique to reduce Noise, magnetic attraction and Twitching sensation

Explanation:

Changing magnetic fields cause loud knocking noise this can be overcome by ear protection.

Strong and Static magnetic fields attract magnetic objects that can be avoided by screening of people and objects before entering in that area.

Twitching Sensation due to nerve stimulation can be avoided by reducing the exposure to magnetic field.

When a flat slab of transparent material is placed under water, the critical angle for light traveling from the slab into water
Novosadov [1.4K]

Answer:

(a) 40.6 degree

Explanation:

When refraction takes place from slab to water, the critical angle is 60 degree.

Use Snell's law

refractive index of water with respect to slab

\mu _{w}^{s}=\frac{Sin60}{Sin90}

\frac{\mu _{w}}{\mu _{s}}=0.866

\frac{1.33}{\mu _{s}}=0.866

μs = 1.536

Now for slab air interface, the critical angle is C.

\mu _{a}^{s}=\frac{SinC}{Sin90}

\frac{\mu _{a}}{\mu _{s}}=\frac{SinC}{Sin90}

1 / 1.536 = Sin C

C = 40.6 degree
