Answer:

Explanation:

The relationship between angle and wavelength for maxima and minima in Young's double slit experiment is given by

For constructive interference

d\sin \theta =m\lambda

For Destructive interference

d\sin \theta =(m+\frac{1}{2})\lambda

where \lambda =wavelength

d=slit\ width

m=order of maxima and minima

for second order maxima i.e. m=2

For smallest separation taking \lambda =400 nm, \theta =90^{\circ}

d\sin 90=2\times 400\times 10^{-9}

d=0.8\times 10^{-6}

d=0.8\mu m

Sketch the path that light would take through the slit. Show the beams that are incident on and reflected from the mirror. Draw
satela [25.4K]

This is the path of light through slits.

what are incident light ?

The light that hits a topic is called as incident light. It may originate from an artificial source or from a natural source, like as the sun. Incident light is also light that reflects off a reflector or another surface.

what is light ?

The region of the electromagnetic spectrum that the human eye sees as light, or visible light, is composed of electromagnetic radiation. The Sun is the primary source of natural light on Earth. Fire has historically been a major source of light for people, from ancient campfires to modern kerosene lamps. Electric lighting has largely taken the place of firelight as a result of the development of electric lights and power systems.

At 7:00 pm the police discovered a body in a hotel room which maintained a constant temperature of 24 degree C. At the time of d
schepotkina [342]

Explanation:

According to Newton's law of cooling,

T(t)=T_s+(T_o-T_s){e^{{-t/\tau}}

T(t) is the temperature at time t

T_s is temperature of surrounding

k=\dfrac{1}{\tau}

At the time of discovery, the temperature of the dead body was, T_o=36^{\circ}C

Temperature of the surrounding, T_s=24^{\circ}C

Temperature after 4 hours, T=30^{\circ}C

So, 30=24+(36-24)e^{-4t}

On solving the above equation,

k = 0.1735

Now, put the value of k in equation (1) at T = 36 degrees C

We know that, the temperature of body before death is T(t) = 37 degrees C

37=24+(36-24)e^{0.17t}

On solving above equation,

t = -0.46 hour

As time can't be negative and we have taken 7:00 pm as reference time.

So, t = 27.67 minutes

So, the death of the person is at 6 : 32 pm. Hence, this is the required solution.
