CP Physics B Module 07

Front

What is Hooke's Law?

Back

Hooke's Law states that the force exerted by a spring is directly proportional to the displacement of the spring from its equilibrium position, expressed as F = -kx, where F is the force, k is the spring constant, and x is the displacement.

Front

How do you calculate the displacement caused by a weight attached to a spring?

Back

Displacement (x) can be calculated using Hooke's Law: x = F/k, where F is the weight (force) and k is the spring constant.

Front

What is the formula for the wavelength of a wave?

Back

The wavelength (λ) can be calculated using the formula: λ = v/f, where v is the wave speed and f is the frequency.

Front

What is the relationship between frequency and period?

Back

Frequency (f) is the reciprocal of the period (T), expressed as f = 1/T. If the period is 10 seconds, the frequency is 0.1 Hz.

Front

What is a standing wave?

Back

A standing wave is a wave that remains in a constant position, typically formed by the interference of two waves traveling in opposite directions.

Front

What is the difference between mechanical waves and electromagnetic waves?

Back

Mechanical waves require a medium (solid, liquid, or gas) to travel through, while electromagnetic waves can travel through a vacuum.

Front

What is the fifth harmonic in a closed tube?

Back

The fifth harmonic in a closed tube corresponds to the frequency that produces five quarter wavelengths within the length of the tube.

Front

How do you determine the length of a closed tube for a standing wave?

Back

The length of a closed tube (L) can be determined using the formula: L = n(λ/4), where n is the harmonic number and λ is the wavelength.

Front

What is the speed of a wave?

Back

The speed (v) of a wave is calculated using the formula: v = fλ, where f is the frequency and λ is the wavelength.

Front

What is the unit of spring constant (k)?

Back

The unit of spring constant (k) is Newtons per meter (N/m).
