Question 12

Visible light

Answer 12

Only type of EM wave that are seen to humans, White light, used by optic organs of
most animals to see

Question 13

Ultraviolet light

Answer 13

Harmful to living things, situated beyond the visible spectrum at its violet end —used of radiation having a wavelength shorter than wavelengths of visible light and longer than those of X-rays, security images, black light, and sterilize medical equipment (SME)

Question 14

X-rays

Answer 14

Tiny wavelength and high energy waves, medical imaging and airport security

Question 15

Gamma rays

Answer 15

Shortest wavelength and has the highest energy, cancer cell treatement, (SME)

Question 16

Spectroscopy

Answer 16

the study of the properties of light that depend wavelength

Question 17

When is a spectrum produced?

Answer 17

A spectrum is produced when white light passes through a prism

Question 18

Continous spectrum

Answer 18

Produced by an incandescent solid, liquid, or

compressed gas, uninterrupted band of color

Question 19

(dark lines) Absorption Spectrum

Answer 19

Produced when white light is passed through a
comparatively cool, low pressure gas, appears as a continuous spectrum but with dark
lines running through it

Question 20

(bright lines) Emission Spectrum

Answer 20

Produced when white light is passed through a
comparatively hot, incandescent gas, appears dark but with individual bright lines
running through it

Question 21

Doppler effect

Answer 21

The apparent change in wavelength of
radiation caused by the relative motions of
the source and observer

Question 22

Blueshift

Answer 22

light where spectral lines are shifted to

the blue end of the spectrum (moving closer to an object/planet)

Question 23

Redshift

Answer 23

light where spectral lines are shifted to

the red end of the spectrum (moving further away from an object)

Question 24

Cataracts

Answer 24

a clouding of the lens of the eye or of its surrounding transparent membrane that obstructs the passage of light

Question 25

What is Refraction?

Answer 25

When a wave crosses the boundary between two media at an angle , the decreased wavelength causes light to bend.

Question 26

Prism

Answer 26

A transparent optical device that can refract light

Question 27

Dispersion

Answer 27

The ability to sperate white light and into a spectrum

Question 28

Visible spectrum

Answer 28

The colors or when white light is separated

Question 29

What did Herschel discover in his experiment?

Answer 29

Herschel discovered that the greatest heating occurred in the infrared portion of the Sun’s spectrum.

Question 30

What is an example of a logitudinal wave?

Answer 30

A sound wave is example.
