Answer 1

@Somy

Answer 2

The answer is marked in red; the problem is we don't know how to look at the question...

Answer 3

Not sure how to use this equation in this though T= λ/c

Answer 4

i understood that the formula used is
\[ \frac{ 1 }{ f } =\frac{ \lambda }{ v } \]
meaning
\[T =\frac{ \lambda }{ v }\]

Answer 5

Answer 7

NO IDEA

Answer 8

lol

Answer 9

@KissMyAxe ....?

Answer 10

U sure it is C

Answer 11

Marking scheme man...=_=

Answer 12

Got it!

Answer 13

there are thee wave fronts, which means distance is 3 lambda so apply v = f lambda
\[v = f \lambda\]

Answer 14

ehm it's women, no?

Answer 15

waaaaaaaaaaaaait how do u know that its 3?

Answer 16

thanks @thushananth01 :)

Answer 17

owh got it so those lines represent 1 lambda?

Answer 18

Yes somy

Answer 19

i mean from 1 line to another

Answer 20

\[c = f \times 3 \lambda\]
\[f = \frac{c}{3 \lambda}\]
\[\frac{1}{t} = \frac{c}{3 \lambda} ----t = \frac{3 \lambda}{c}\]

Answer 21

Yes

Answer 22

yes woman or yes lambda?

Answer 23

Lambda

Answer 24

oh okay noted! :D
