Answer
given,
wavelength of the red light,λ = 687 nm
wavelength of the yellow light = 582 nm
Frequency of red light
=
=
= 4.36 x 10¹⁴ Hz
frequency of the yellow light
=
= 5.15 x 10¹⁴ Hz
speed of the car
v_r is the required speed.
v_r = 0.19 c
v_r = 0.19 x 3 x 10⁸ =5.7 x 10⁷ m/s
1 m/s = 2.23694 mile/hr
v_r = 1.27 x 10⁸ mile/hr
if the light is actually yellow
f₀ = 5.15 x 10¹⁴ Hz
f = 6.13 x 10¹⁴ Hz
wavelength corresponding to this frequency is wavelength = 493.2 nm
hence, the color corresponding to this wavelength is Green.
From the first condition
1 = vo t
From the second condition
1 = 8.2 (t - 12/60)
The time it takes to travel 1 mile in the second condition is
t = 0.32 hr
The original speed is
1 = vo (0.32)
vo = 3.13 mi/h
Answer:
The angle of incidence is equal to the angle of reflection.
Explanation:
angle of incidence (i) = angle of reflection (r)
So if the angle of incidence was 45°, the angle of reflection would also be 45°.
Answer:
A
Explanation:
I’m not sure but I hope this helped
