1. A student carries out an experiment to investigate the relationship between the depth ofwater, d, and the wavelength, λ, of water waves with its frequency kept constant. The

apparatus set up for this experiment is shown in iagram 1.1.Seorang murid menjalankan satu eksperimen untuk menyiasat hubungan antara kedalamanair, d, dengan panjang gelombang, , bagi gelombang air yang !rekuensinya dimalarkan.Susunan radas bagi eksperimen ini ditunjukkan dalam "ajah #.#.

!ater is poured into the ripple tank until the depth of water, d is 1." cm. Then, the powersupply and motor are switched on to start the vibration of the vibrator. A stroboscope is usedto observe the bright and dark bands on the white paper placed below the ripple tank. Thefirst and the last dark bands are marked as A and # respectively. The distance of separationbetween two successive dark bands equals the wavelength, λ, of the water waves. Thenumber of λ between A and # is counted. iagram 1.$ shows the reading of the wavelength,λ, when the depth of water, d % 1." cm.

Air dituang ke dalam tangki riak sehingga kedalaman air, d ialah #.$ %m. &emudian, bekalankuasa dan motor dihidupkan untuk memulakan getaran penggetar. Sebuah stroboskopdigunakan untuk memerhatikan jalur %erah dan gelap di atas kertas putih yang diletakkan di

bawah tangki riak itu. Jalur'jalur gelap yang pertama dan terakhir masing'masing ditandakansebagai A dan B. Jarak pemisahan antara dua jalur gelap berturutan bersamaan panjanggelombang, , bagi gelombang air itu. Bilangan antara A dan B dibilang. "ajah #.2menunjukkan ba%aan panjang gelombang, , apabila kedalaman air, d ( #.$ %m.

The experiment is repeated with the depth of water, d % 1.& cm, $." cm, $.& cm, and '." cm.The corresponding readings of the wavelength, λ are shown in iagrams 1.',1.(,1.& and1.).)ksperimen diulangi dengan kedalaman air, d ( #.* %m, 2.$ %m, 2.* %m dan +.$ %m. Ba%aan

4 (a) Inference : The Crane (b) had attracted more load of scrapped irons than the cranebecause of its larger no. of coils/turns of the solenoid // the strength of the magnetic fielddepends on the no. of turns/coils of the solenoid.

1

(b) Hypothesis : Bigger number of turns in the solenoid , the stronger will be itselectromagnetic field strength 1

(c) Aim : To investigate the relationship between the number of turns and theelectromagnetic field strength 1

Variables : Manipulated : number of turns in the solenoidResponding :electromagnetic field strength / no. of pins attracted 1

Constant Variable : Current soft iron core . 1

!ist of apparatus : Solenoid, VC tube ! large iron nail , iron nails! pins!paper clips,ammeter , rheostat and po"er supply.

"rrangement of apparatus:

1

Control of Manipulated Variable : #ind the insulated wire around the large iron nail/$%Ctube , starting with &' coils . 1

Measurement of Responding Vble : !ower the solenoild until it touches the iron nails. ecord the number of iron nails attracted b it. 1
