Answer:
The angle is 25.34°.
Explanation:
Given that,
Wave length = 650 nm
Angle = 68.0°
We need to calculate the distance
For a diffraction grating



We need to calculate the angle
Using formula for angle




Hence, The angle is 25.34°.
Answer:
the answer is that the circuit is open,
Explanation:
if you look towards the switch its off, or open meaning no current can flow
Answer:E. an object will remain in uniform motion unless acted upon by a force
Explanation:
Through satellites they launch into space.
If you have a string that is fixed on both ends the amplitude of the oscillation must be zero at the beginning and the end of the string. Take a look at the pictures I have attached. It is clear that our fundamental harmonic will have the wavelength of:

All the higher harmonics are just multiples of the fundamental:

Three longest wavelengths are:
