Semester Test Study Guide

Front

What type of wave are radio waves?

Back

Electromagnetic waves are waves that can travel through a vacuum and do not require a medium.

Front

Which type of electromagnetic wave is the most dangerous to humans?

Back

Gamma waves and higher frequency/shorter wavelength waves are the most dangerous to humans.

Front

What happens to the Earth if the force of gravity from the sun is turned off?

Back

The Earth would move in a straight line away from the sun instead of orbiting it.

Front

If a dancer exerts a force of 200.0 N to lift his partner with an acceleration of 2.50 m/s², what is the mass of his partner?

Back

The mass of the partner is 80 kg.

Front

Which color of visible light has the longest wavelength?

Back

Red light has the longest wavelength in the visible spectrum.

Front

What is the definition of electromagnetic waves?

Back

Electromagnetic waves are waves that consist of oscillating electric and magnetic fields and travel at the speed of light.

Front

What is the relationship between frequency and wavelength in electromagnetic waves?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is the formula to calculate force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is the significance of gamma rays in the electromagnetic spectrum?

Back

Gamma rays have the highest energy and shortest wavelength, making them highly penetrating and dangerous.

Front

What is the effect of gravity on objects in space?

Back

Gravity keeps celestial bodies in orbit and affects their motion.
