1st Semester Science Final Exam 100 Questions

Front

What is the difference between electromagnetic waves and mechanical waves?

Back

Electromagnetic waves can travel through a vacuum (space) and do not require a medium, while mechanical waves require a medium (solid, liquid, or gas) to travel.

Front

What question can determine if a wave is electromagnetic or mechanical?

Back

Can the wave travel through the vacuum of space where there is not matter?

Front

What happens to a horizontally thrown ball if gravity did not affect its path?

Back

The ball would travel horizontally.

Front

When is the bicycle’s acceleration the greatest if the motion is graphed?

Back

From 8-9 seconds.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another due to a change in speed.

Front

What does it mean if a color of light refracts the least?

Back

It means that the color has the longest wavelength and is less affected by the medium.

Front

What is the role of a prism in light behavior?

Back

A prism separates white light into its component colors by refraction.

Front

What is amplitude in wave physics?

Back

Amplitude is the maximum extent of a wave's displacement from its rest position, indicating the wave's energy.

Front

What is the definition of acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t).
