A wall clock has a minute hand with a length of 0.53 m and an hour hand with a length of 0.26 m. Take the center of the clock as

ollegr [7]

Answer:

a =1.61 × 10⁻⁶ m/s²

Explanation:

given,

length of minute hand = 0.53 m

length of hour hand = 0.26 m

the time taken by the minute hand to complete one revolution is T=3600 s

the angular frequency is

$\omega =\dfrac{2\pi }{T}$

$\omega =\dfrac{2\pi }{3600}$

$\omega=0.001745 rad/sec$

the acceleration is

$a = r \omega^2$

$a = (0.53) \times (0.001745)^2$

a =1.61 × 10⁻⁶ m/s²

a nearly monochromatic beam of light with an average wavelength of 514 nm is incident normally on a diffraction grating 1.30 cm

muminat

smallest wavelength difference (in nm) this grating can resolve in the second order diffraction with this beam is 8 degree

The formula for diffraction grating: Obviously, d = \frac {1} { N }, where N is the grating constant, and it is the number of lines per unit length. Also, n is the order of grating, which is a positive integer, representing the repetition of the spectrum so in this case the wavelength difference can be calculated as 514 nm/ 1.30 X 110 =3.59 X2 =approx 8.Wavelengths between 100 nm and 10 m correspond to the optical regime, where grating application is most prevalent. In that situation, the groove density can range from a few tens to a few thousand grooves per millimeter, similar to echelle gratings.
