Answer:
you got to add the chart my g
Explanation:
Answer:
1.33
Explanation:
Using the formula for destructive interference since the two reflected ray light waves from eyeglass should be made to cancel each other ( destructive interference) and also refractive index of air less than the refractive index of the film and both are less than the refractive index of the glass meaning the both reflected rays from the air and film will experience a phase change
n film = ( m + 0.5) ( λ / 2t)
since 2 t = ( m + 0.5) ( λ / n film)
where m is an integer, λ is wavelength, and t is thickness and n film is the refractive index of film
for effectiveness m = 0
n film = ( 0.5) ( 480 ÷ (2 × 90 ) ) = 1.33
Alpha Centauri is 4.4 lightyears away. Traveling at 1/10 speed of light it would take you 44 years.
The given are:A
djacent/Hypotenuse = sin 35°
Height(h) - Adjacent
Hypotenuse- a length of a side:
We will use the formula:
sin (angle) = op/hyp
sin 35° = h/ 4.1 m
0.57356 = h / 4.1 m
h = 0.576576 ·
4.1 = 2.35166 ≈ 2.4 m
Answer: the top of the slide is 2.4 m above the ground which is letter d.
