Answer:
6.67 minutes
Explanation:
d = Diameter of first telescope = 2 m
d' = Diameter of second telescope = 6 m
Increase in diameter
Time to collect light for first telescope
t = 1 hour = 60 minutes
Time to collect light for second telescope
The time taken would be 6.67 minutes
Answer: The yellow light with a frequency equal to 5.21 x 1014 Hz will have a wavelength of E) 576 nm
Answer:
Explanation:
For light passing through a single slit, the position of the nth-minimum from the central bright fringe in the diffraction pattern is given by
where
is the wavelength
D is the distance of the screen from the slit
d is the width of the slit
In this problem, we have
is the wavelength of the red light
D = 14 m is the distance of the screen from the doorway
d = 1.0 m is the width of the doorway
Substituting n=1 into the equation, we find the distance between the central bright fringe and the first-order dark fringe (the first minimum):
I believe the givens should be written in this manner,
(4.2 x 10⁵)(4.0 x 10⁻⁹)
To answer, we first multiply the bases 4.2 and 4 which will give us,
16.8
Then, we multiply the multipliers by adding up the exponents of 10. This will give us the answer of,
16.8 x 10⁻⁴
Then, the final answer would be 1.68 x 10⁻³.
