Answer:
Constructive interference: destructive interference
Explanation:
Constructive interference occurs when waves are in phase or sync with one another and will lead to brighter and bolder results while destructive interference occurs when waves are out of phase with one another.
In this scenario, light passing through two slits creates a pattern of bright and dark fringes on a screen. The bright fringes result from constructive interference ; the dark fringes result from destructive interference.
The solution would be like this for this specific problem:
Given: 5973 K
λ_peak = 2.898 / 5973 K
= 0.00048518 mm = 0.48518 μ = 4851.8 Ậ
Polaris emits peak radiation at 485 nm wavelength.
To add, Polaris, commonly the North Star or Pole
Star, is the brightest star in the constellation of Ursa Minor.
Answer:
In Celsius:
Explanation:
The formula we are going to use is:
Where:
ε is the emissivity
σ is the Stefan constant
is the final temperature of surrounding surfaces
is the required temperature
is the are of surrounding surface
Calculating The area:
σ=
ε =0.95
=55+273
=328 K
=100 W
In Celsius:
Given: Mass m = 5.00 Kg; Height h = 12 m; Time t = 15 s
Required: Power P = ?
Formula: P = Fd/t = mgh/t
P = (5.0 Kg)(9.8 m/s²)(12 m)/15 s
P = 39.2 Kg.m²/s² or
P = 39.2 J
