The distance between successive wave crests defines the ____________________ of a wave.
Which of the following has a fundamentally different nature than the other four?- photon, proton, electron, neutron
Consider a comet with a period of 7,407 years (there is no need to convert).How many AU is its semi-major axis (i.e. average orbital distance)?
Barnard 68 is a cool, dark galactic gas cloud (aka the Boomerang Nebula).One would expect most of the radiation it emits to be in
Please match each of the following atomic hydrogen lines (from the Balmer Series) to their corresponding wavelengths. The lines are arranged (alpha, beta, gamma, delta) to show increasing frequency (or decreasing wavelength).H- squiggly line thing: H-alpha:H-lambda:H-beta:
Consider two stars, A (red) and B (blue) and their orbits shown below.If Star B has twice the mass of Star A,
Which of these is NOT a form of electromagnetic radiation?- sound, radio, visible light, gamma, infrared
Consider a distant body in our solar system. If its orbit has a semi-major axis of 65 AU (there is no need to convert),how many years does it take to complete its orbit around the Sun?
You observe the Doppler-shifted radiation for two stars, A and B. A's radiation is shifted into the bluer region of the spectrum, while B's radiation is shifted into the redder region of the spectrum. This could mean
The frequency at which a star's intensity is greatest depends directly on its
The speed of light c = 2.99 x 108 m/s. The speed of light is the product of the wavelength (lambda, ) and frequency (f):c= Lambda x fThe metric units for wavelength are meters (m) and Hertz (Hz) for frequency. Calculate the wavelength of a light wave with a frequency of 26,330 Hz.
Refracting telescopes use a mirror to gather and focus light.a. Trueb. False
There is no air on the Moon to scatter light and soften shadowsa. Trueb. False
Seismic waves are classified asa. Pressure and Shear waves.b. Long and Short waves.c. Fast and Slow waves.d. Sound and Earth waves.e. Light and Heavy waves.
the earth is closer to the sun in January. from this fact, kepler's second law tells us
The four diagrams below show the orbit of the same comet, but each one shows the comet moving through a different segment of its orbit around the Sun. For each segment, a line drawn from the Sun to the comet sweeps out a triangular-shaped, shaded area. The shaded regions have exactly the same area.Rank the segments of the comet’s orbit from left to right based on the distance the comet travels when moving from Point 1 to Point 2, from largest to smallest.
which of Galileo's initial observations was the most challenging to geocentric beliefs?
how did the geocentric model account for day and night?
Einstein revolutionized modern physics by ____.a. explaining how specific gravity impacts the geometry of curved space-timeb. documenting the existence of gravity through experiments on objects in motionc. proving that Galileo and Newton were fundamentally incorrect about gravityd. providing an explanation of gravity based on the geometry of curved space-timee. defining the difference between violent motion and natural motion
