Attached to a spring vibrates back and forth. At the equilibrium position, the
velocity reaches a maximum
A system in simple harmonic motion, which of the following is the number of
Cycles or vibrations per unit of time?
·The highness or lowness of a sound is perceived as a
·The Doppler Effect occurs with
Portion of the electromagnetic spectrum is used in a television?
Vacuum, electromagnetic radiation of short wavelengths
a. Travels as fast as radiation of long wavelengths.
The following best describes the image produced by a flat mirror?
C. Virtual, upright, and magnification equal to one
Of mirror is used whenever a magnified image of an object is needed?
·Part of a
Pencil that is placed in a glass of water appears bent in relation to the part
Of the pencil that extends out of
The water. What is this phenomenon called?
Of light can change when light is refracted because the medium changes.
Of image does a converging lens produce?
C. Real or virtual
Lightbulbs are placed side by side, no interference is observed because
b. Incandescent light is incoherent
Process of charging a conductor by bringing it near another charged object and
The grounding the conductor is
Is used to describe a perfect radiator and absorber of electromagnetic
Nodes and antinodes?
a phenomenon that occurs when the frequency of a force applied to a system Matches the natural frequency of vibration of the system, resulting in a large Amplitude of vibration
While light passing through a prism produce a visible spectrum?
Refraction happens as light enters and leaves a prism. Red light is Refracted the least and violet light is refracted the most. This causes the Different colors in the light to spread out to form a spectrum. Separating the Colors like this is called dispersion.
Four fundamental interactions and their corresponding particles in order from
Weakest to strongest.
Gravitational, weak nuclear, electromagnetic, strong nuclear
Ways to induce a current in a circuit loop using only a magnet
1. Place it in a changing magnetic field; 2. Change the area of the loop; 3. Change the orientation of the loop with respect to the magnetic field.
