2. To elevate in terms of status: The promotion will raise Pete's colleague to a managerial position at the factory.
3. To enhance or to invigorate: Such a sunny day will raise Jill's spirits.
4. To collect funds to finance a special undertaking: Carl hopes to raise a large sum of money to contribute to the children's charity.
5. To bring an animal or child to maturity: There is a saying which indicates that it takes a village to raise a child.
6. To inquire about or to bring forth a topic for discussion or debate: Terry said he would raise the question of new prices for bus tickets at the next board meeting.
7. To cause the creation of a blister or sore: If Marissa does not wear gloves when she rakes leaves, the friction will raise blisters on her hands.
8. To increase the bid or offer on something: At the auction, the auctioneer attempted to raise the amount on the priceless piece of silver.
9. To increase or to cause the elevation of the baseline of something: The heavy rains will raise the level of the river.
The landlord told Etta that he was going to raise her rent significantly the following year.
2. Beams of light: The sun rays shined through the window illuminating the room and making it feel warm and comfortable.
3. Lines drawn from a common center: Shelby depicted the sun by drawing several rays emanating from the round yellow circle in the corner of her picture.
The carver used a small knife to raze the surface of the block of wood he was working on so he could make an ornament.
They had to raze the old building and build a new one so the sun’s rays wouldn't raise the temperatures so much.
A landlord told his tenant, "I'm afraid I will have to raise your rent." The renter responded by saying, "I wish you would; I'm sure I can't raise (get) it."
2. A stream of electrons projected by radioactive substances.
They are identical with cathode rays, possess great penetrative power, and are easily deflected by an electric or magnetic field in a direction opposite to that of the alpha rays.
2. A high-energy photon, especially as emitted by a nucleus in a transition between two energy levels.
2. Streams of ionizing radiations from space, largely of protons, alpha particles, and other atomic nuclei.
3. Very high energy nuclei moving at velocities close to that of light which are probably produced by supernova explosions.
On striking the earth's atmosphere, they produce cascades of other particles (by collision with nuclei in the atmosphere) called air showers.
Because the earth’s atmosphere absorbs X-rays very efficiently, X-ray telescopes and detectors must be carried high above it by spacecraft to observe objects that produce such electromagnetic radiation.
Advances in instrumentation and improved observational techniques have led to the discovery of an increasing number of X-ray sources.
By the late 20th century, thousands of these objects had been detected throughout the universe.
