How has modern digital signal processing affected analyses done using Fourier transforms on complex waveforms when compared with analog methods?
Caused dependency on hardware capabilities limiting experiments to easily replicable scenarios only.
Imposed restrictions necessitating specialized software hindering interdisciplinary applications across fields.
Diluted fundamental understanding due to reliance on 'black box' algorithms without insight into underlying mathematics.
Greatly increased speed and accuracy in decomposing signals into constituent frequencies.
During which phenomenon does light behave most noticeably as wavelength rather than particles?
Refraction
Photoelectric effect
Reflection
Diffraction
What difference would be observed if coherent light were used instead of incoherent light for Young's double-slit experiment?
No visible interference pattern forms using either type of light.
Dark fringes become less pronounced while bright fringes remain unchanged with coherent light.
Stable interference pattern with clear bright and dark fringes appears with coherent light.
Brightness of individual slits increases but no interference pattern emerges with coherent light.
If a wave's frequency is halved while its speed remains constant, what happens to the wavelength?
The wavelength halves.
The wavelength doubles.
The wavelength remains unchanged.
The wavelength quadruples.
When a charged particle moves perpendicular to a magnetic field, what path does the particle follow due to the magnetic force?
Parabolic
Elliptical
Straight line
Circular

When light of a certain frequency is shone on a metal surface and electrons are emitted, this phenomenon best demonstrates which aspect of wave-particle duality?
The diffraction pattern of particles.
The particle nature of light.
The interference pattern of waves.
The wave nature of light.
What effect does increasing fluid density have on sound waves traveling through it?
There are no significant effects on sound speed but attenuation increases dramatically.
Sound speed increases as greater mass provides more momentum transfer between particles.
Sound wavelength decreases while frequency stays constant leading to decreased velocity.
Sound speed decreases as fluid density increases due to increased inertia opposing particle motion.
What term describes the bending of waves as they pass from one medium to another at an angle?
Refraction
Diffraction
Reflection
Interference
