The correct answer to the question is Visible light.

EXPLANATION:

A rainbow is visible to our naked eye. It contains all the seven constituent colors of a white light ranging from violet to red. Generally it is formed after a storm. It is due to the fact that different colors of light has different wavelength. When the white light falls on the water particles present in the atmosphere, all the colors deviate at different angles after their refraction through water particles, and the spectrum is obtained.

The infrared wave, X- rays and ultraviolet rays are not visible to our eye.

The visible light is that electromagnetic wave which helps us to view any object. It contains the seven colors just like a rainbow i.e ranging from violet to red.

All the colors present in a rainbow corresponds to visible region of the electromagnetic spectrum .

Hence, visible light is that electromagnetic wave which makes up the colors of a rainbow seen after a storm.

Explanation:

Since the frequency of sound heard is higher than actual frequency, the ambulance is moving towards you!

The frequency of sound waves as heard from a distance for a sound wave coming towards one at v₀ m/s and whose real frequency is f₀ is given by

+f = f₀/[1 - (v₀/v)]

+f = frequency of sound as heard from the distance away = 8.61 KHz

f₀ = real frequency of sound = 7.87 KHz

v₀ = velocity at which the sound source is moving towards the reference point = ?

v = velocity of sound waves = 343 m/s

8.61 = 7.87/(1 - (v₀/v))

1 - (v₀/343) = 0.9141

v₀/343 = 1 - 0.9141 = 0.0859

v₀ = 343 × 0.0859 = 29.48 m/s = 64.945 miles per hour

Answer:

$t = 0.192 \mu m$

Explanation:

Path difference due to a transparent slab is given as

$\Delta x = (\mu - 1) t$

here we know that

$\mu = 1.79$

now total shift in the bright fringe is given as

$Shift = \frac{D(\mu - 1)t}{d}$

Also we know that the fringe width of maximum intensity is given as

$\delta x = \frac{\lambda D}{d}$

now we have

$\frac{D}{d} = \frac{\delta x}{\lambda}$

now the shift is given as

$Shift = \frac{(\mu - 1) t \delta x}{\lambda}$

given that the shift is

$Shift = 0.37 \delta x$

here we have

$0.37 \delta x = \frac{(\mu - 1) t \delta x}{\lambda}$

now plug in all values in it

$0.37 = \frac{(1.79 - 1) t}{411 \times 10^{-9}}$

$t = 0.192 \times 10^{-6} m$

$t = 0.192 \mu m$
