Vladimir79 [104]

Answer:3.6

Explanation:

Given

Architect decide to double the width

length increases by 50 percent

height increases by 20 percent

Let L,B,H be length,height and width of rectangular room

L'=1.5L

B'=2B

H'=1.2H

therefore new volume V'=L'\times B'\times H'

V'=1.5L\times 2B\times 1.2H

V'=3.6LBH

new volume is 3.6 times the original

If a transparent blue filter is placed over a camera lens, what happens to visible light entering it
Leya [2.2K]

Answer:

B

Explanation:

If you pass white light through a blue filter, then only blue color will appear on the other end. This is because a blue filter will only allow blue light through it. And will absorb other color. In other words the rest colors would disappear. Hence the camera would receive just blue light. This phenomenon is referred to as color by subtraction.

krek1111 [17]

Answer:

Explanation:

The path length difference = extra distance traveled

The destructive interference condition is:

\Delta d = (m+1/2)\lambda

where m =0,1, 2,3........

So, ←

\Delta d = (m+1/2)\lamb da9/tex]so [tex]\Delta d = \frac{\lambda}{2}

⇒ λ = 2Δd = 2×10 = 20
