Question 11 (2 points) Question 11 Unsaved
Which statement best describes the difference between ultraviolet light and infrared light?

While both are at the end of the spectrum where wavelength is shorter, ultraviolet has the longer wavelength.

While both are on the high frequency end of the spectrum, ultraviolet has the higher frequency.

While both are on the high radiant energy end of the spectrum, ultraviolet has the lower radiant energy.

While both are at the end of the spectrum where frequency and wavelength are decreasing, ultraviolet has the higher radiant energy.

Question 12 (2 points) Question 12 Unsaved
What is the primary reason that astronomers put telescopes and other instruments above Earth's atmosphere?

The atmosphere absorbs the infrared light coming in from the sun.


The instruments can better view the universe without the distraction of electromagnetic rays emitted by the earth.


The instruments can get closer to the objects they are observing at the extreme ends of the universe.


The atmosphere blocks or absorbs UV, gamma, and x-rays emitted by processes taking place in the universe.

Question 13 (2 points) Question 13 Unsaved
How have scientists proved that supernova explosions occur?

Bursts of gamma rays are given off during supernova explosions that can be detected by special instruments.


Photons of light travel to Earth, allowing astronomers to see the explosion through a telescope.


Infrared rays emitted by a supernova explosion allow scientists to create a thermogram of the event.


Ultraviolet rays produced when a supernova explodes are detected on Earth using special sensors.

Which statement correctly explains refraction?

Question 14 options:

Light slows down as it passes through objects and causes them to appear to be disconnected.


Light speeds up as it passes from air to water, causing an interruption in the light ray that creates the image.


Light slows down as it passes from air to water, and this causes the object to appear curved.


Light bends as it passes at an angle from one medium into another, causing the image to appear bent.

Answer:

question 11 :........ultraviolet has high frequency.

..........ultraviolet has higher radiant energy

question22 :......the instruments can better view the universe without the disruction of electromagnetic rays emmited by the earth.

......the instrument can get closer to the object they are observing at the extreme end of universe.

And question 14 : Light speed up as it passes from air to water causing an interruptionin the light ray that create the image.

Light bends as it passes at an angle from one medium into another,causing the image to appear bent.

(it's not 22 question it's 12 question sorry).

I only know that.
