Answer: A and C (i took the test)
Explanation: Hope this helps:)
Explanation:
speed of wave
v = wavelength x frequency
since frequency is f = 1/Period then
v = wavelength : Period
v = 10 cm/ 0.2 s = 50 cm/s
v = 0.5 m/s
three charged particals are located at the corners of an equil triangle shown in the figure showing let (q 2.20 Uc) and L 0.650
Answer:
The speed of the laser light in the cable,
Explanation:
It is given that,
Wavelength of Argon laser,
Refractive index, n = 1.46
Let is the speed of the laser light in the cable. The speed of light in a medium is given by :
or
So, the speed of the laser light is . Hence, this is the required solution.
