Question

The ratio of density of 2 substance is 4 ratio 3 and their specific heat capacity is in the ratio 3 ratio 6.Find thr ratio of their heat

Answer 1

Explanation:

l

amplitude of the light in the bright region = A1+A2

amplitude of the light wave in dark/low intensity region = A1 - A2

ratio of intensities = (A1-A2)² /(A1 + A2)² = 1 : 9     given

 =>  (A1-A2)/(A1+A2 ) = 1/3

A1-A2)/(A1+A2 ) = 1/3 =>  A1 /A2 = 2 : 1

Ratio of amplitudes = 1 : 2    or   2 : 1

Ratio of intensities of the interfering waves :  = A1² / A2² = 4 : 1

The two intensity of the interfering waves that pass through a slit is dependent on the amount of light passing through the slit.  So intensity is proportional to the slit width.  (Slit breadth is same for both slits.)

   Hence 1

Answer 2

Explanation:

The ratio will be 4 : 1 .....lol
