OSTP Semester 1 Review

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Formula: F = ma (Force = mass x acceleration).

Front

What type of waves have the longest wavelength?

Back

Radio waves have the longest wavelength compared to visible light, X-rays, and gamma rays.

Front

How do you calculate frequency?

Back

Frequency is calculated by counting the number of complete waves that pass a fixed point in a given amount of time. It is measured in Hertz (Hz).

Front

What is frequency in terms of waves?

Back

Frequency is the number of complete waves passing a fixed point in a given amount of time.

Front

What does wavelength represent in a wave?

Back

Wavelength is the distance between two consecutive points of the same phase in a wave, such as crest to crest or trough to trough.

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is amplitude in a wave?

Back

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

Front

What is the formula for calculating wave speed?

Back

Wave speed can be calculated using the formula: Wave Speed = Frequency x Wavelength.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle displacement is perpendicular to the direction of wave propagation (e.g., light waves). In longitudinal waves, the particle displacement is parallel to the direction of wave propagation (e.g., sound waves).

Front

What is the unit of frequency?

Back

The unit of frequency is Hertz (Hz), which represents one cycle per second.
