Two sounds of 50 db each will NOT constitute a 100 db sound. This is because, the relation that relates levels of sounds is a logarithmic relation and not a direct relation of addition. <span>Each 10 dB increase in sound makes the sound 10 times louder.
</span>This means that, for 50 db, the resultant sound level will be <span>twice as loud is an increase of 10Log (2) = 3.01dB
</span>
The final sound level = 50 + 3.01 = 53.01 db

Find the angle for the third-order maximum for 591 nm wavelength light falling on a diffraction grating having 1460 lines per ce
Marat540 [252]

Answer:

15.32°

Explanation:

We have given the wavelength \lambda =591nm=591\times 10^{-9}m

Diffraction grating is 1460 lines per cm

So  d=\frac{10^{-2}}{1460}=6.71\times 10^{-6}m (as 1 m=100 cm )

For maximum diffraction

dsin\Theta =m\lambda here m is order of diffraction

So 6.71\times 10^{-6}sin\Theta =3\times 591\times 10^{-9}

sin\Theta =0.264

\Theta =15.32^{\circ}
