Answer:
D) 1000 m/s
Explanation:
You have the wavelength and frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.
Hope this helps.
c A ray of light is divided into its constituent colors by the first prism (left), and the resulting bundle of colred rays is reconstituted into white light by the second. Our modern understanding of light and color begins with Isaac Newton (1642-1726) and a series of experiments that he publishes in 1672.

The earth is cooled and its atmosphere is heated by terrestrial radiation.
Divide the number of watts by 1000 to convert the number from watts to kilowatts. 60W divided by 1000 results in 0.06kW. Multiply the number of kilowatts by the number of hours the device will be used. If the device will be used for three hours, multiply 0.06kW by three to produce 0.18kWh.
Answer:
Explanation:
12 degree = (π / 180) x 12 radian
= .2093 radian
position of third bright fringe = 3λ D/ d where λ is wave length of light , D is screen distance and d is slit separation
given
3λ D/ d = 30 x 10⁻²
angular separation
3λ / d = .2093
from the two equation
.2093 D= 30 x 10⁻²
D = 30 x 10⁻² / .2093
= 1.43 m
