Answer:
Inside the film the wavelength will be λ/n
For constructive interference to occur the film must be λf/4 thick where λf is the wavelength of the light in the film - there will be a 180 degree phase shift at the water/film interface since the index of refraction of the film is greater than that of water - and the light has to travel λ/2 inside the film for constructive interference to occur
280 nm / 1.6 * 4 = 700 nm is the greatest wavelength allowed
Note that 700 nm is also the upper wavelength of the visible spectrum
Answer:
1 × 10⁶ N/C
Explanation:
The magnitude of the electric field between the membrane = surface density / permittivity of free space = 10 ⁻⁵C/ m² / (8.85 × 10⁻¹²N⁻¹m⁻²C²) = 1.13 × 10⁶ N/C approx 1 × 10⁶ N/C
Answer:
15.13 m/s

is the tension on the rope and
is the density of the rope per unit length

Answer is B hope this helps
Multiple point perspective is a system of perspective in which: A. there are a number of vanishing points, usually created by multiple objects.
<h3>What is
multiple point perspective?</h3>
Multiple point perspective can be defined as a system of perspective in which each items (objects) has a number of interacting lines with different vanishing points.
This ultimately implies that, a multiple point perspective is a system of perspective which is created with a number of vanishing points, that are usually created by multiple objects.
