Phoenix [80]

Answer: The domain that is aligned with the applied field will grow, while the domain that is oppositely aligned to the magnetic field will shrink, this is because permanent magnets produces their own magnetic field.

A pair of slits, separated by 0.150 mm, is illuminated by light having a wavelength of λ = 643 nm. An interference pattern is ob

kumpel [21]

Answer:

0.006 m

Explanation:

d = separation between the slits = 0.150 mm = 0.150 x 10⁻³ m

λ = wavelength of the light = 643 nm = 643 x 10⁻⁹ m

D = distance of the screen where interference pattern is observed = 140 cm = 1.40 m

δ = Path difference

Path difference is given as

δ = Dλ/d

δ = (1.40) (643 x 10⁻⁹)/(0.150 x 10⁻³)

δ = 0.006 m

Green light can have a wavelength of 512 nm. The energy of a photon of this light is

Nat2105 [25]

Answer:

$E = 3.88 * 10^{-17} J$

Explanation:

Energy is directly proportional to frequency and it is given as:

E = hf

where h = Planck's constant

f = frequency

To get frequency, we use the formula of speed:

c = λf

where c = speed of light

λ = wavelength

=> f = c/λ

Therefore, the energy of the photon will be:

E = hc/λ

$E = \frac{6.626 * 10^{-34} * 3 * 10^{8} }{512 * 10^{-9} }$

$E = 3.88 * 10^{-17} J$

The energy of the photon is $3.88 * 10^{-17} J$
