Two narrow slits 84 mum apart are illuminated with light of wavelength 650 nm. what is the angle of the m = 3 bright fringe in radians what is the angle in degrees

The angle is 1.33°.

Explanation:

Given that,

Distance

Wavelength = 650 nm

Number of fringe = 3

We need to calculate the angle

Using formula of angle for brightness

Where, d = distance

=wavelength

m = number of fringe

Put the value into the formula

Hence, The angle is 1.33°.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
