What is a light curve and how can it be used to identify a nova or supernova?
A light curve is a graph showing the brightness of an astronomical object over time. In the case of novae or supernovae, their light curves exhibit a rapid increase in brightness followed by a gradual decrease. By analyzing the shape and characteristics of the light curve, astronomers can determine the type and nature of the astronomical event, helping to identify whether it is a nova or a supernova.
Why does light curve on the earth?
Light curves on Earth due to the planet's curvature. As light travels through the atmosphere, it refracts (bends) slightly. This refraction causes the light to curve downward, following the Earth's surface rather than traveling in a straight line.
A blackbody curve relates the wavelength of emitted light to?
the intensity of radiation emitted at that wavelength, giving a characteristic spectral distribution that depends only on the temperature of the object emitting the light.
What is the possible explanation of the shape of the curve showing the effect of increasing light intensity on the rate of photosynthesis?
The curve typically starts with a steep increase in photosynthesis rate as light intensity increases, as more energy is available for the process. This is followed by a plateau where the rate levels off, indicating that other factors like temperature or enzyme availability are limiting the rate of photosynthesis. Finally, the curve may even decline at very high light intensities due to damage to the photosynthetic machinery.
What is a curve that is higher on the outside than it is on the inside called?
A banked curve.
What is a light curve?
Light
How does light curve at all?
Light does not bend.
What is a light curve graph?
A light curve graph that displays an object's brightness over time mostly used in variable star astronomy.
What is a polar curve in terms of illumination?
The term "polar curve", in relation to the subject of illumination refers to the spread of light from a source. If the curve is weak, then little illumination is provided, whilst the opposite is true for a strong curve.
How does light travel in various mediums?
Along a geodesic curve.
Why don't your Blackberry Curve's keys light up?
yes they do.
How can light curve data be used to study the variability of a celestial object?
Light curve data can be used to study the variability of a celestial object by tracking changes in its brightness over time. By analyzing the patterns and fluctuations in the light curve, astronomers can gain insights into the object's properties, such as its rotation rate, presence of companions, or changes in its activity.

What frequency ranges the radiation curve do red green and blue light occupy?
Red, Blue and Green light occupy a very narrow, but unbroken, part of the full range of electromagnetic radiation curve
What colour light should it flash when a blackberry curve is charging?
Red, i think.
What percentage of light energy absorbed does this peak represent?
The peak's area under the curve represents the percentage of light energy absorbed. To calculate the percentage, divide the peak's area by the total area under the curve and multiply by 100.
How does the curve in a lens cause it to refract light differently from a flat piece of glass?
The curve in a lens causes light rays to either converge or diverge, which leads to refraction. In a convex lens, the curved shape causes the light rays to converge, focusing them to a point. In a concave lens, the light rays diverge, spreading out as they pass through the lens.
