You perform a double‑slit experiment in order to measure the wavelength of the new laser that you received for your birthday. Yo
Vitek1552 [10]

Answer:

λ = 5.734 x 10⁻⁷ m = 573.4 nm

Explanation:

The formula of the Young's Double Slit experiment is given as follows:

\Delta x = \frac{\lambda L}{d}\\\\\lambda = \frac{\Delta x d}{L}

where,

λ = wavelength = ?

L = distance between screen and slits = 8.61 m

d = slit spacing = 1.09 mm = 0.00109 m

Δx = distance between consecutive bright fringes = \frac{4.53\ cm}{10} = 0.00453 m

Therefore,

\lambda = \frac{(0.00453\ m)(0.00109\ m)}{8.61\ m}

<u>λ = 5.734 x 10⁻⁷ m = 573.4 nm</u>

The earth's orbital angular speed in rad/s due to its motion around the sun
Anna71 [15]

           (2π rad/year) x (1 yr/365 days) x (1 day / 86,400 seconds)

       =    (2π) / (365 x 86,400)        rad/sec

       =        0.000 000 2  radian/sec

       =          0.2 microrad/sec

Which is the wavelength of a wave that travels at a speed of 3.0 × 10^8 m/s and has a frequency of 1.5 × 10^16 Hz?
k0ka [10]

Answer:

2 x 10^-8

Explanation:

the formula of wavelength is

the speed divided by frequency

so you have the speed given = 3.0x10^8m/s

and frequency = 1.5×10^16 Hz

so wavelength = 3.0x10^8m/s / 1.5x10^16 Hz
