Lightwaves travel from the air into a lens made of glass. their velocity decreases as they enter the glass. how does this affect the frequency and wavelength of the lightwaves? a. their frequency stays the same and their wavelength increases. b. their frequency stays the same and their wavelength decreases. c. their frequency increases and their wavelength decreases. d. their frequency decreases and their wavelength increases.

B. their frequency stays the same while the wave length decreases.

Explanation:

As the light wave travels from a less dense medium to a denser medium it slows down and this causes refraction. The speed of light is given by wavelength×frequency.

Therefore, when the wavelength decreases, the speed also reduces.

answer is B.

Explanation:

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

thats a little if u want the answer just look it up on google thats what i do haha : )
