Answer:
1.092 cycles
Explanation:
We need to convert the arc length of 6.86 radians into cycles.
We know that,
1 radian = 0.1592 cycles
To convert 6.86 radians to cycles, we use unitary method.
6.86 radian = (0.1592 × 6.86) cycles
= 1.092 cycles
Hence, there are 1.092 cycles in 6.86 radians. Hence, this is the required solution.

Answer:
refraction
Explanation:
When waves, including light, pass through two media with different densities, the waves bend at the transition between the two media due to differences in speed and wavelength. Convex lenses bend (refract) light and concentrate it at one point called the focal point.
hope this helps
The frequency of a beam of light does not change as it passes from a medium to another, only its wavelength and speed are affected. The experimental speed of light in air is:
3 * 10^8 m/s
Therefore, the frequency of this beam of light is:
v = fλ; where v is speed, f is frequency, and λ is the wavelength. The frequency thus is:
3×10⁸ / (670 × 10⁻⁹) = 4.48 × 10¹⁴ Hz
The frequency will remain the same in the solid medium
The speed will then become:
4.48 × 10¹⁴ × 420 × 10⁻⁹ = 1.88 × 10⁸ meters per second
