What is the wavelength in nm of a light whose first order bright band forms a diffraction angle of 30 degrees, and the diffracti
Artist 52 [7]

Answer:

The wavelength is 3500 nm.

Explanation:

d= \frac{1}{700 lines per mm} = 0.007mm = 7000 nm

n= 1

θ= 30°

λ= unknown

Solution:

d sinθ = nλ

λ = \frac{7000 nm sin 30}{1}

λ = 3500 nm

This physics problem is kinda complicated to my small brains...
Veronika [31]

Answer:

\huge\boxed{\sf P.E. = 14700\ Joules}

Explanation:

This work done is in the form of Potential Energy so we'll use the formula of Potential Energy.

<u>Given Data:</u>

Mass = m = 250 kg

Acceleration due to gravity = g = 9.8 m/s²

Height = h = 6 m

<u>Required:</u>

Work Done in the form of Potential Energy = P.E. = ?

<u>Formula:</u>

P.E. = mgh

<u>Solution:</u>

P.E. = (250)(9.8)(6)

P.E. = 14700 Joules

\rule[225]{225}{2}

Hope this helped!

What is an oscillation on waves?
Tasya [4]
The number of repetitions per second is called the frequency and is the inverse of the period. The period, T, is normally measured in seconds, and the frequency, ν, in Hertz. When the oscillations<span> (or vibrations) affect the material around them a </span>wave <span>is formed which transports energy away.</span>
