Final Exam Review (PL) - Part 2

Front

What is the definition of Wavelength?

Back

Wavelength is the distance between successive crests or troughs of a wave, typically measured in meters.

Front

What happens to wavelength as frequency increases?

Back

As frequency increases, wavelength decreases.

Front

What is Diffraction in the context of waves?

Back

Diffraction is the bending of waves around obstacles and openings, which can cause interference patterns.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). It can be expressed as V = I × R.

Front

What is the relationship between frequency and energy of a wave?

Back

The energy of a wave is directly proportional to its frequency; higher frequency waves carry more energy.

Front

What is the definition of Amplitude?

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium.

Front

What is the difference between Reflection and Refraction?

Back

Reflection is the bouncing back of a wave when it hits a surface, while refraction is the bending of a wave as it passes from one medium to another.

Front

What is the highest frequency color in the visible spectrum?

Back

Blue light has the highest frequency in the visible spectrum.

Front

How do you calculate voltage in a circuit?

Back

Voltage can be calculated using Ohm's Law: V = I × R, where V is voltage, I is current, and R is resistance.

Front

What is the definition of Crest in a wave?

Back

Crest is the highest point of a wave.
