What is the Sagnac effect in the context of gyroscopes?

• A phenomenon where light travels faster in a rotating medium

• The change in the speed of sound in a rotating object

• The deviation of a compass needle due to Earth's rotation

• The phase shift in the interference pattern of light beams in a rotating ring laser gyroscope

 In what type of environment are RLGs typically housed to maintain their accuracy?

• 
• 
•

In modern aircraft avionics, MEMS gyroscopes are often used for what purpose?

• Controlling cabin temperature

• Monitoring engine performance

• Measuring aircraft's roll, pitch, and yaw

• Managing in-flight meals

MEMS gyroscopes contribute to improved aviation safety by enhancing what critical aspect of flight?

• In-flight Wi-Fi connectivity

• Fuel efficiency

• Aircraft stability and control

• Passenger comfort

Which physical effect is the basis for how MEMS gyroscopes detect changes in rotation?

• Sagnac Effect

• Coriolis Effect

• Doppler Effect

• Newton's Third Law

• Newton's Second Law

Coriolis effect explaination:

When the device experiences angular rotation, the proof mass (a tiny vibrating structure within the gyroscope) also experiences Coriolis forces due to its inertia.
